I solved it! Somehow I had a corrupt google-chrome.desktop in my ~/.local/share/applications/ folder. I found the file in /usr/share/applications/ was valid. After deleting the bad one in my ~/.local/share/applications/ folder, logging out and back in, everything is back to normal. I can select Google Chrome from Default Applications and everything is ...

You should be able to set Chrome as default browser directly from Chrome settings. Have a look at the icon on top right of any Chrome tab (the three lines) and then Settings --> Default browser.

Unfortunately, there are no such preferences available in Firefox anymore. Mozilla has removed all such functionality.

Accidental fix. Long story short: Go to the url: about:config. It will warn you that it's dangerous. Continue Look for browser.download.lastDir. There's a search bar at the top. Double-click the browser.download.lastDir row. A prompt will appear. Edit as needed. Click Okay. Close your browser to refresh. Following this link in Mozilla's FAQ, I saw how ...

An easy way to do this is to edit your mimeapps.list to make your preferred browser your default email client, then setting up your browser to use your preferred webmail service as the default handler for mailto: links. Here's how I did it, using Inbox by Gmail as my webmail service and Chrome as my default browser. Edit ...

Okay, so we found the solution for this problem. First of all there was a wrong argument number if the netbeans.sh file. So url=$2 should be url=$1. But also the parsing of the filename and the line number in the script was wrong. Since the provided string has the form netbeans:///path/to/file?line=[LineNumber] the parsing can be done by: #!/bin/bash # ...

The description for that PPA clearly states: Mozilla Security/Stability testing archive for Ubuntu. So: No, don't install that! I would: Install NoScript (I did this years ago and never looked back) Disable JS everywhere, except on secure, trustworthy sites Turn off the sound and notifications in NoScript: it becomes much less annoying after ...

Take a look at this webpage: https://help.ubuntu.com/community/WebBrowsingSlowIPv6IPv4 In particular the section titled: Blackhole IPv6 route I made the change last nite to /etc/sysctl.conf and added: net.ipv6.conf.all.accept_ra = 0 Then rebooted... its been almost 24 hours now and I'm not seeing any Firefox browsing delays any more.

I've tried several things now to fix this on my system but I think I may finally have a solution as I made the change last night and so far have gone all day & several reboots without any slow browser lookups etc. I'd heard some time ago about possible problems with IPv6 DNS lookups and that while not specifically an IPv6 problem it had more to do with ...

Disabling ligatures (see Calimo's fonts.conf answer) is the wrong direction! It may remove those over-aliased "bold" ligatures in fonts like Calibri, but it also removes some of the beauty of typography. That's rather similar to shrinking the font until you can't tell the difference. I solved this for my system by removing the Calibri font, installing ...

I found that firefox doesn't actually use the Downloads folder. Instead it puts everything in /tmp/mozilla_username0

I have been researching this to, as i didn't want Chrome/Chromium, but it seems that it's not going to work with Firefox anymore. They 'dropped it'. http://linux.softpedia.com/blog/canonical-drops-all-ubuntu-specific-firefox-extensions-492676.shtml

I have found Zoneminder to be a power hog so I don't use it. I have not had any luck using VLC. Foscam requires a plugin which sometimes works with Wine+Firefox+myfoscam.com. I have never been able to use myfoscam.com in Ubuntu+Firefox. I have had success using Ubuntu+Chrome+MyIpCam-apt from the Chrome store. My Netgear server forwards port 88 to the ...

Or when you don't want to change your desktop files you can simply edit : ~/.mozilla/firefox/profiles.ini and change line StartWithLastProfile=1 to : StartWithLastProfile=0

The solution is adding www.youtube.com###guide-container to any adblocker (uBlock in my case) solved the freezing Problem and disabled the left side Menu. 👍👍

In the end, after an update to Firefox 44 everything works again, more or less... I don't know if it's really solved, since it's still notably slower than Chrome, but at least is usable. A few days ago I tried the nightly (ver 46) and it had the same problem, so I already started despairing that an update wouldn't solve... But actually it did, so I'm happy. ...

The current version of Firefox is 44.0, released on January 26. The current version of Firefox on Ubuntu on any supported release is 44.0, and it's only been a day. I don't know what more you could ask for in the name of updates.

Firefox gets updates from Ubuntu official repositories. If you have a supported version of Ubuntu, you should have the latest version of Firefox with security updates. If this is not the case, then you have an EOL version of Ubuntu, or you did something wrong that prevents regular updates. You can install the latest Firefox version by running in terminal: ...

Check out (type as url): about:support This should give you info on supported features (like hardware rendering) You can try to disable/uncheck hardware acceleration in Firefox. It may feel counter intuitive but has often worked for me. You can find it here: Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when ...

Possibly the only use that I personally have for Chrome is to make a 'Netflix App' out of it. google-chrome-stable --app=http://netflix.com Running that, or editing the launcher for Chrome to run this command will open Google Chrome and launch the netflix website without any pesky window dressing like a location bar, buttons, tabs.....just Netflix. Of ...

Ok, I'm answering my own question: the problem was with the jnlp file format itself, and I had the parsing error I overlooked. It had to do the the format of the href attribute of the jnlp tag containing some question marks (see https://stackoverflow.com/questions/14112318/the-reference-to-entity-subset-must-end-with-the-delimiter)

You should - make sure that gstreamer1.0-libav plugin is installed then in firefox address bar go about:config, search mediasource & enable media.mediasource.webm.enabled & media.mediasource.enabled That should allow playback on twitter as long as the 1st. 2 mentioned below are not enabled or you enable all 3 If you want full coverage in ...

This problem is definitely add-on/extension related. Restarting with add-ons disabled in Firefox safe mode resolves the issue. Note that simply disabling or removing ad block plus does not work. How: https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode In my case I had flashblock installed and disabling it from firefox addon ...

This is not a program but it is a simple trick I use quite often. Firefox and Thunderbird will underline misspelled words with a red line. Move the cursor under the misspelled word and press the menu key on your keyboard. This will bring up a context menu and suggested spellings will be listed at the top of this menu. Use the arrow keys to select the ...

Works now with firefox 43. Since gstreamer is replaced with ffmpeg.

You can use Pepper Flash in firefox. Pepper Flash is basically Chrome's Flash API. Chrome has this API installed by default (You might notice this when you have a fresh install of Windows/Linux and Chrome doesn't need to install flash while other browsers do). Here are the steps: Open terminal by clicking the Ubuntu logo, the Super key or press Ctrl+Alt+T ...

Could it be hardware acceleration? Try firefox safe mode. If firefox hangs, press CTRL-ALT-F1 and log in from console. Kill firefox (killall firefox, or killall -9 firefox). Log out and get back with CTRL-ALT-F7 Edit: (provided the computer is not too badly locked, of course)

Long story short: change audio output device to something else and then back to the desired device Full version: I know it's bit outdated, but still. I've just run into similar problem on Ubuntu GNOME 15.10 - everything worked apart Firefox. I remember lately using my laptop with TV via HDMI and changing sound output to it. Today, in my "Sound" ...

One possible cause is a conflict between the KDE theme and GTK. I had the same problem because ~/.kde/env contained a file gtk2-engines-qtcurve.rc.sh with export GTK2_RC_FILES=$HOME/.gtkrc-2.0-kde4 Commenting out the export, logging out and in again fixed the dark grey on black problem for alternate text.

Never mind. I have script blockers that were preventing the needed Javascript from running right. White-listing the domain wasn't enough. I had to tweak other settings.
