This is a known issue in Firefox versions that use GTK3 (like the recently released v46.0). See this Bugzilla ticket for background information. In short, the support for non-local files in the file chooser has changed with GTK3 and Firefox would now explicitly have to support remote files. If you don’t need this feature very often, then there may be a ...

One solution is to edit the userContent.css for firefox. I had this issue previously with the Ubuntu Software center and did something similar. You can find a related post about it here: http://forums.fedoraforum.org/showpost.php?p=1703251&postcount=3 I am not sure if this fix still works since the 16.04 update, but it should be applicable.

For some reason, the language packs are separate packages that do not get uninstalled if you uninstall Firefox. However, you can safely uninstall the language pack. Just do sudo apt-get remove firefox-locale-[your version]. If removing this would happen to remove other packages that depend on the language pack, it will tell you so and you can cancel the ...

Make sure the gtk2 and gtk3 themes match so the appearance is consistent across applications. Downloading new themes to find something that work for your preference is a worthwhile option. Personally, I use KDE instead on gnome, and updating to firefox 46.0 forced me to change my gtk3 theme because the oxygen-gtk theme wasn't working.

Here's how I fixed the black screen issue. With a reduced page size (so that the screen wouldn't black out) I went to the Mozilla website. The site automatically determined that I was using the latest version but offered the option (with a big green button) to "Refresh" the browser. When I refreshed, the browser worked properly, and continues to work ...

I solved my problem, but my attempts to make the applet work using OpenJDK-8 and the IcedTea-8 plugin were unsuccessful. If anyone can find a method that avoids using Oracle Java (which is proprietary), that will be a big improvement on this answer. I am using 64-bit Ubuntu 16.04 and the Firefox version that came with it; presumably something along these ...

This behavior is expected. In the “new” section of the release notes of Firefox 46, there is the following bullet: GTK3 integration (GNU/Linux only) That means that Firefox tries to look like most other (GTK3) applications starting with version 46. For example, open the text editor gedit and right click in the open window there: it also shows a black ...

Had to uninstall this PPA. The rest of the instructions worked as expected, and my original Firefox profile was restored. sudo ppa-purge ppa:ubuntu-mozilla-daily/firefox-aurora

Firefox is now GTK3 based, Chrome is still GTK2 based., so that's not that easy. You will have to edit your theme or use a theme that supports this. Since GTK3 is very new in firefox some themes can have problems, though I personally like GTK3 better. You could add a bookmark to ./config/gtk-3.0/bookmarks, nano ./config/gtk-3.0/bookmarks and see if that ...

same problem here with Firefox 46 on Ubuntu 14.04 LTS although the appearance is not exactly the same: scrollbar is a very light gray, I can't see anymore which part of the page is in the main window. It is a light gray button on a light gray background!!! I tried to see if the the Classic Theme Restorer extension could help but for the moment, I did ...

Not sure if it will work because I don't have this issue but my firefox is synced with my windows system and that may be why. If you click on the button in the right top corner (where you would click to get to preferences) then click on Customize in there you should see themes .. maybe try selecting a different theme might set it right.

What you could do is to install and use a complete theme for Firefox that includes its own scrollbars etc. This won't look like the old default, but I bet you can find something similar or even nicer. In the Tools menu, select Add-ons, there go to the Get add-ons tab and scroll down the page. In the lower left corner is a link See all complete themes. This ...

In Ubuntu 16.04 support for the overlay/Unity scrollbars was dropped in favor of the Gnome scrollbars. The relevant bugs concerning the old scrollbars have been closed as won't fix. Since Firefox didn't use GTK3, however, even those didn't work when 16.04 was released. Firefox 46, however, finally includes GTK3 integration, so the Gnome scrollbars are now ...

I believe it is a problem with Firefox 45 and 46, I had the same. Firefox 47 seems to work much better, you can download the binaries from here: https://ftp.mozilla.org/pub/firefox/releases/45.1.0esr/linux-x86_64/en-US/

I know it's a bit late answer, but anyway, I'll leave this here for anyone that might want to know and finds this looking for a solution. I solved this annoying issue by switching from nautilus (default file manager of ubuntu) to caja. I don't understand why did the ubuntu team or nautilus team this change, but it's annoying as hell to me, I have to ...

I had a similar problem, but I managed to solve it as follows; I downloaded the .deb package from google, but it seems the new Gnome-based software center did not install it properly. So, instead, I used sudo dpkg -i <*package*>. Worked for me. P.S.: I was confused for a while with Chromium vs Chrome. They are different projects, and only ...

I had a similar problem. Sometimes it is impossible to prevent applications from trying to adjust the microphone level. With Ubuntu, it is at least possible to prevent ALSA from responding to such requests. In the configuration file /usr/share/pulseaudio/alsa-mixer/paths/analog-input-internal-mic.conf (you might have to look for the correct file for your ...

Figured it out. Somehow, firefox tried to stream the audio to some airplay speakers on the network. (something that actually never worked). This caused the video to stall. Killing the WIFI (network) allowed the video to play and send audio to the local device, re-enableling the network caused it to stall again...

Chromium does not support Netflix because of the lack of a needed component. You can manually install this component, but it's a hassle and not really worth it. Firefox doesn't support Netflix either, at least as of 2014. If you want Netflix on Ubuntu, you need to use Google Chrome. Download the DEB file from Google's website. More details: ...

Searching some more I found that this seems to be a known bug actually: https://bugs.launchpad.net/canonical-pocket-desktop/+bug/1543351 This is the latest comment at this point: kevin gunn (kgunn72) wrote on 2016-04-15: #6 just confirming, this is definitely on our todo list as a high priority.

The most up-to-date one should be available from the Software Center on a supported version of Ubuntu, perhaps you should make sure that your software sources are up-to-date by running the Software Updater or this in Terminal (CTRL + ALT + T): sudo apt-get update If you still do not get the latest then you are either running an End-Of-Life version of ...

Yes, it totally depends on your decision. But I think /opt is OK, remember in the /etc make a separate folder first: sudo mkdir YOURFIREFOXFOLDERNAME After you successfully installed Firefox, click on the Dash and search for "firefox". When you find it, open it: Next, if you want to have it all the time on the Launcher, just right click on the Firefox ...

Using locate was a good idea, but Firefox extensions are referred to by UUIDs, unique names rather than human readable ones to prevent different extensions from having the same name. As NoScript's is 73a6fe31-595d-460b-a920-fcc0f8843232, you should find: locate *73a6fe31-595d-460b-a920-fcc0f8843232* to be more helpful.

Disclaimer: not sure this will work. It might overwrite the current profile. Best to make a backup of the old profile before attempting. Run firefox -P Click "Create profile". Follow the instructions. When you get the option, click "choose folder" and select the location of the old profile. Finish the creation of the new profile. Once you're back at the ...

One solution is to go ahead and copy the link location. Then paste the URL into the address bar in Chrome. To save time,have Chrome running the background before you open Thunderbird. Probably better, though, is to install the add-on called "Open-With" by Geoff Lankow. This allows you to select on the fly the browser you want to open a particular link. You ...

There was a folder "Old Fireforx Data" on my desktop that I missed when I asked the question. I moved the folder inside it (called "hb0i6k54.default") into ~/.mozilla/firefox and edited profiles.ini in that folder so that it would point to hb0i6k54.default - and that fixed the problem.

It was because of ZenMate extension in my FF. Even I switched it off from browser's toolbar it still interfere with this setting. I bypassed this problem by disabling ZenMate extension in FF settings.

It is possible to do so. One could write a wrapper script , which will launch a process and capture its PID and monitor for that PID. For instance, I've written a small script bellow, that if called like monitor_process.sh firefox will launch firefox and wait till it exits. #!/bin/bash nohup $@ &> /dev/null & PID=$! while ps --no-headers -p $PID ...

This works for me ... Create a folder called bin in your home directory if such a folder doesn't already exist.

Open Firefox go to help menu and pick Restart with Add-ons Disabled click restart. when it reopened a new tab will appear. Find Refresh Firefox and go through. This is the ultimate solution I've tested on Ubuntu 14.04. I hope to be useful for you as well.
