Firefox Support Forum

I upgraded Firefox to 109.0 on OpenSUSE Linux today as an update. Firefox no longer plays videos. Chrome is still playing the videos, so the codecs are on my machine. Is there anything I can do to fix this?

Hello, Since my last update, Firefox 93, my bookmarks present a huge line spacing between them, line spacing that I would like to control to see more bookmarks at a time. Do you know how to proceed ? Thank you very much.

On my laptop, I run FDE as my daily driver, with the release version to handle my webmail. I also use portable firefox (from portableapps.com) as a browser to use while at work, from a thumb drive. While using that portable verison, I usually just go to google image search, and a work site that would definitely be secure.

My question: I don't like to update the installation on my thumb drive very often, and occasionally work computers are very slow anyways. So if I were to update it no more often than once a month, which version of firefox would be most secure: Release, Beta, or Nightly?

If doing this is just dumb, then which version gets updated less often--it would be Release, correct?

Hello,

I am a Web Developer, fixing a website for my client. After the page is cached in Mozilla Firefox the layout breaks, when I clean the cache everything is back to normal. This issue is only present in Mozilla Firefox, I don't have that issue with Google Chrome.

Website URL: https://www.impeccablex.com/ Please see the screenshots attached, you can see the layout before and after.

I have tried almost everything that I could think of, don't know what to try next. Any suggestions?

Thank you in advance! Best Regards, Mario C.

I'm not sure this is a problem with Firefox but I have run out of other options to look at. At first I thought it might be because the page uses a frameset (I know it's obsolete) so I created a version that uses an iframe instead. That way the html that needs to be acted on is not in a frame. It still doesn't work. I don't know why it works in stackoverflow's sandbox and jsfiddle but not on my website. Any help is appreciated.

Frameset version iFrame version

If you need to see the tabstrip code (it's virtually identical to the iFrame version): Tabstrip for frameset version

The script is supposed to hilite the selected tab with a red background. The rollover works fine (yellow background and brown text) but the selected tab color never shows up.

The blocks where code should be displayed like on screen and on stackoverflow displayed in a weird manner : replaced with [Object object] i don't have any extensions that might cause that

Hello! I am in a work environment and I am trying to determine if there is something in our security systems that is preventing Firefox from running properly. Once Firefox is installed, it works the rest of the day with no issue but almost daily the morning after, it will start to open then instantly crash. When I check the crash logs, it shows in most of them: Modules - Filename: umppc14210.dll Version: 6.28.14210.0 Debug Identifier: B9143DE260194C88AB48EFD6782C9EAF1 Debug File Name: umppc.pdb Signed By: Microsoft Windows Hardware Compatibility Publisher

Some are this instead: Filename: umppc14105.dll Version: 6.27.14105.0 Debug Identifier: CE458B39D37A4C65A60024BBACED6EB31 Debug File Name: umppc.pdb Signed By: Microsoft Windows Hardware Compatibility Publisher

When using the dark theme from Firefox, Google searching seems to break completely as well as some pages will not load which may be related to this.

I have already tried uninstalling Firefox, deleting all of the folders, then reinstalling with a freshly downloaded installer (Even tried the beta one) with same results. It seems potentially MAYBE related to how long ago I closed Firefox before I shut down (Like Firefox is trying to save something to a secure location and times out, then it will work but if it hasn't timed out, then it crashes... or this is my guess)

The Signature seems to change randomly for the crash between crashes.

I really am tired of constantly reinstalling Firefox but I do not want to use Chrome or Edge unless websites require it.

Last few days any Firefox 102.0.1.8221 launch causes my Windows 7 64bit to reboot, usually when I try to mouse click anything in Firefox after it's fired up and restored open tabs, however even if I don't mouse click anything Firefox will force a reboot within a minute or so.

This Firefox Win 7 reboot behaviour only started after the last Firefox update, though I would point out that around update version 100.nn I started getting failed update notifications from within Firefox which necessitated a manual newer version Firefox download and install.

Running Windows 7 in safe mode with networking on allows Firefox to function without crashing, albeit slowly and with no MSE protection available etc.

Only one crash report dated 16/07/2022 with following content: Crash ID: bp-d8383165-9c77-45e4-9929-a3ce12160527

Please note I'm sending this report via Firefox on my iMac coz that still works...

When I copy text from other websites, I'm not able to paste in the text field of Whatsapp Web. I'm using Firefox Developer Edition Browser in my laptop. But when I copy text from Whatsapp Web itself, I am able to paste in the text field.

This issue started happening just a few days ago.

Here are my specifications:

Browser: Firefox Developer Edition 117.0b8 (64-bit)

OS: Pop!_OS 21.10

Hello,

Currently running MacOS Montery but the problem was still occurring on previous versions.

Whenever I use the green top left button to enter full-screen, the app immediately freezes and either crashes or has to be manually force quit. There are no reports in about:crashes and I there has been no success with troubleshooting mode or switching versions of the Firefox application.

Machine Info: MacBook Pro (16-inch, 2019) Processor: 2.6 GHz 6-Core Intel Core i7 Memory: 16 GB 2667 MHz DDR4 Graphics: Intel UHD Graphics 630 1536 MB

Any help towards a solution would be appreciated. Thanks!

I have used Firefox with my Outlook email account for years. This morning when I open my email it displays the message list briefly then goes to "Something Went Wrong."

Microsoft has confirmed it's not my computer and not on their end.

Updating to latest Firefox does not work.

I noticed the toolbars had changed positions and thought I'd use the customize page to see if I could reorganize them. Somehow I ended up with the usual three toolbars, but bookmarks are on the top (tabs) toolbar, not the bottom (bookmarks) toolbar, which is empty. This is Ubuntu 21, firefox 95.0b2.

Top: Starting on the far left are the Ubuntu window controls, my bookmarks. and tabs. Middle: The customized URL/search bar. Bottom: The bookmarks toolbar, which is empty. I know this is so because CTRL-SHIFT-B hides and shows it.

I can drag bookmarks on the top(tabs) toolbar around, reorganize them, and and delete bookmarks and folders, but always only on the top (tabs) toolbar. I cannot drag any of them to the bottom (empty bookmarks) toolbar.

Hi,

I've been encountering a strange issue where colors (especially whites) in the video player are super washed out. This only happens when HDR is turned on in windows, and only happens in my Firefox Developer Edition installation (normal firefox works fine). It also doesn't show up in any windows screenshots - the colors revert to normal when I'm in the screenshot GUI. I've attached photos below of a youtube video, the left is firefox DE and right is normal firefox, both in and out of the screenshot GUI so you can see the difference.

I'm on Windows 11, and I'm not sure what caused the issue. I've tried both refreshing and reinstalling firefox DE to no avail. Pretty stumped on this one, and would appreciate any help!

Since upgrading to Monterey, Google search pages show almost no text in Firefox. Google searches in Safari and Google Chrome are completely fine. Only Firefox is showing the problem. The blank text includes dropdown menus too - all options inside them are blank. Currently on Firefox v107.0, but the same problem happens with older versions.

If I go into Troubleshoot mode, the Google searches are working fine. I have refreshed Firefox, Cleared the startup cache. But the problem persists. I uninstalled Firefox from the machine, restarted the computer. Did a fresh download and install, haven't signed in so there are no addons/extensions to cause problems.

This is happening on both an Intel Mac and an M1 Mac running Mac OS 12.6 Monterey.

I attach one screenshot showing the same page with and without troubleshoot mode on. The second screenshot shows another page of results including what looks like weirdly encoded characters.

I've followed all the suggestions in the support page but nothing has helped. I'd really appreciate any advice on further troubleshooting. Thanks in advance for any help.

I've got about 10 bookmarks with links to support pages each about adjusting specific about:config setting to my needs. My job also requires me to change systems lots of times, from Mac to windows to Linux. Is there an easy way I can save my personal about:config changes to a file for easy import on other systems?

Thanks

I am using firefox just for a few days, then when I go in to my Add-ons setings, it said All add-ons have been disabled by safe mode. So what is safe mode how can I turn it off!?
