I'm still using a regular, spinning disk and Firefox is constantly waking it up.

Virtually any action taken (especially closing a tab, any tab) causes the above. I moved ~/.mozilla and ~/.fonts to a tmpfs which once used to be enough to make the disk spin-ups reasonable but not any more.

I changed the disk cache dirs

browser.cache.disk.parent_directory → string → /tmp browser.cache.offline.parent_directory → string → /tmp

to /tmp, which is also a tmpfs. Then I disabled disk cache

browser.cache.disk.enable False browser.cache.memory.enable True

but nothing seems to stop this crazy behaviour. What more can I do?

I looked through lsof and strace, Firefox seems to also be using /var/cache/fontconfig/ and .cache/fontconfig/ do I need to move those, too?

This is on Ubuntu 13.04 with Firefox 21.

One hour ago I was happily watching youtube videos under Linux using Firefox 20.0 and flash 11.2. I just updated firefox and it is now blocking my flash and prompting me to update. The problem is I can't update because 11.2 is the LAST flash plugin for firefox, there won't be any other version.

Is there a way to prevent firefox from disabling my plugin?

Pages with web fonts, like http://google.com/fonts, are not rendered correctly. All text that should be web fonts is shown with the default font. This is Firefox 20.0 on Ubuntu 13.04 with Gnome 3.8. - Starting in safe mode does not help. - neither does starting with a new blank profile. - There are no error messages in the Error Console. - Javascript is enabled. - not allowing hardware acceleration does not help. - the "Allow sites to use their own fonts" option is checked. - I am not behind a proxy.

What else is there to check?

I was using a theme which increased the height of tabs. Unfortunately, the theme conflicted with tab menu setting using the TabMixPlus extension. I am stuck with the default theme or others which do not increase the tab height. I have tried a variety of codes in userChrome.css to no avail. I am presently using the default theme with Firefox 20.0.1 (a Linux operating system).

I'm running firefox 20 on linux (opensuse 12.3) and this doesn't display properly some website... This look like:

I thought the problem was the Unicode but I had changed the codification to UTF-8 and the problem persist Some suggestions for solve this. Thanks!

I've installed a firefox marketplace app for my desktop firefox that I'd to uninstall it now, but I can't seem to find where they're actually listed at.

I can't see them in the add-ons page, nor does going to about:apps show anything

The Windows 7 version of Firefox has the option to show each tab as a separate item on the taskbar. I am using Linux now (specifically, Linux Mint, MATE desktop with compiz) and I miss that feature. In compiz, I can press Super+W to show all of my windows at once on the screen. This doesn't help though, because only the active tab exists on the taskbar and in the view of all windows.

If it is not possible to show all tabs as taskbar items, is there a way to set up firefox to not use tabs, and to just make a new window when it would make a tab?

Hi,

I have a slight problem with the firefox sessionrestore on ubuntu (13.04 64bit). Every time I login after a shutdown/logout and open firefox it opens all the tabs and windows I had when shutting down. It seems that firefox thinks it crashed after a reboot since a normal exit/relaunch shows me a single empty page (which i prefer)

After googling a lot of relevant settings about disabling the sessionstore in about:config were suggested but none worked. I'll try to sum up the settings that seem related ot that I changed but can't be sure of all I did, I've been struggling with it for some months (since I changed from chrome to firefox) and didn't document my changes.

I've tried disabling all addons and start a clean profile but that didn't change anything so I reverted to my old profile, I don't have a second pc to test on so I'm not sure if this problem is limited to my setup.

I've set:

• browser.sessionstore.resume_from_crash to false
• browser.sessionstore.max_resumed_crashes to 0
• browser.sessionstore.max_tabs_undo to 0
• browser.sessionstore.max_windows_undo to 0
• toolkit.startup.max_resumed_crashes

Default:

• browser.sessionstore.resume_session_once is false
• browser.sessionstore.restore_hidden_tabs is false
• browser.sessionstore.restore_pinned_tabs_on_demand is false

Is there anything else I can try to test or fix this? Thanks in advance for any help!

How do I eliminate the down-pointing arrowhead to the right of folders in the bookmarks toolbar? I find it redundant, and wish to have more items in that bookmarks toolbar at all times, as Chromium allowed me before I migrated to Firefox.

Mozilla.orgs automated OS detection system is too smart for it's own damn good, preventing perfectly legitimate downloads from being possible (i.e. Linux user wants to download a Windows version for a VM!!)

The genealogy site https://familysearch.org/search is stuck in firefox, even in safe mode.

This applies to linux as well as to windows 7, 64bit, enterprise (FF20.0.1).

The page opens and the blue search bottom is stuck with "Loading". Normally it shows "Search"

The site is working well with IE9.

regards,

Gerhard

I recently put firefox (17.0.5) in full screen for a while on my Linux Laptop running CentOS6 (up to date on 3/5/2013) I never managed to exit this full screen mode, neither with the contextual menu in the tab bar (appeared when I went to the top of the screen), nor with F11. Even when I close and restart Firefox, or when I shut off and restart the laptop, I get back to this fullscreen mode each time I open firefox. Only the failsafe mode (run with the command firefox -safe-mode) is not in full screen, and that was for me the only way to disable all my addons (as recommanded by some similar threads on the support forum). I have no access to any menu, but thanks to the about:plugins special address, I could control that my plugins are off, and e for with about:support I got an overview of my installation, that seem OK. There is also about:config to edit my preferences, but I don't find the one which could be responsible for this behavior. Any ideas?

On loading http://www.google.com and then clicking the "Sign In" it goes to...

https://accounts.google.com/ServiceLogin?hl=en&continue=http://www.google.co.uk/

HOWEVER - I get a report of "This Connection is Untrusted"

...and to add insult to injury, there is no button option to add an exception. Just the "get me out of here"

This is Firefox version 20 - I just updated this morning - on Ubuntu 12.04 64 bit. Connecting through a new Netgear router that I installed this afternoon ... so I can't tell exactly what the heck is going on.

THIS IS URGENT AS NOW I CAN'T ACCESS ANY OF MY GOOGLE SERVICES.

Technical Details

       accounts.google.com uses an invalid security certificate.

The certificate is not trusted because it is self-signed. The certificate is only valid for www.routerlogin.net

Since the last week I cannot get to work facebook properly on firefox (im running it on debian squeeze). It started not loading facebook which was solved by deleting cookies and cache, but now I cannot "interact" with it, It loads the page, but i cannot accept requests, see comments, load other peoples profile, change security settings etc. Whenever i try to do something it keeps on trying to load but it never does

I was using firefox 15, I upgraded it to firefox 20 but the problem is still there.

I am running on Ubuntu 13.04 (kernel 3.8.0-19-generic)

I connect to internet Using Huawei E303 and it's In built Driver Software( Mobile Partner )

When I connect to internet using mentioned device firefox says it s in Offline mode.

But If I refresh 5-6 times it connects to internet. But google-chrome connects at first timeall other applications use internet seamlessly. I thought this might be a proxy issue and I Checked for that; and applied no-proxy system wide.

Firefox connects only after 5-6 times refreshing.

Facebook sets the value of <spellchecker.dictionary> to <ru_RU> every time I start entering text (language doesn't matter) in a textbox on FB.

FF: Firefox 20.0 - Mozilla Firefox for Linux Mint OS: Linux Mint 13

I haven't noticed any other website I use causing that problem: all of them use the predefined (in prefs.js) value of <spellchecker.dictionary> and don't change it unless I change the speller language manually. The only way I can change the value of <spellchecker.dictionary> back to <en_US> is manually choosing English in context menu of a textbox, or editing "prefs.js", every time Facebook messes it up.

Why does FB always sets <spellchecker.dictionary> to <ru_RU>???

My default locale is "en-US": <general.useragent.locale> = "en-US".

Please help.

Firefox 20 on Ubuntu 13.04 under Gnome 3 environment.

Everything works fine, except this happens sometimes, not sure of the cause - The context menu works fine everywhere on all parts of Firefox, on all the bookmarks on my bookmarks toolbar, but for one specific set of bookmarks, namely the ones in the drop down arrow menu for the bookmarks that do not fit on the main toolbar, sometimes context menu for items on that appears entirely disabled (grayed out) though it works fine everywhere else including the bookmarks that are visible on the toolbar. A restart solves this but it happens again.

This doesn't seem to be caused by an extension as I do not have any extensions that modify the bookmarks toolbar or manage bookmarks.

Unfortunately, I use 15 other extensions for different purposes and disabling them one by one and checking everytime for one hour whether the issue occurs again is not a viable solution. Please advise whether this is a firefox bug, or if an issue with extension framework, then how to single out the faulty extension. Thank you.
