Firefox Community Forum

I'm using Firefox 141.0 on OpenSuse Tumbleweed with KDE and Wayland. I'm using Firefox with two profiles: work and personal - which is (usually) awesome, until suddenly it's not.

Then, one or both profiles seem to become corrupted, and closing firefox, opening it, choosing either profile just hangs forever. My old tabs show up, but clicking on any tab, for any site, just hangs forever, and no page is ever loaded. Sometimes restarting helps, but sometimes not. Sometimes restarting 2 or 3 times and then suddenly it will work. But normally, I have to just delete all my profiles, and re-create them. Fortunately everything is synced with Firefox sync. Then everything will work wonderfully for a bit - although I have to re-login to everything.  :-(

Any ideas? This is a huge pain and productivity killer. I really love firefox, but this sucks.

Hello, I'm using Firefox on Linux Mint. All of my homepage shortcuts have disappeared without the option to add them back. I tried toggling the shortcuts option on and off and nothing happens. Nothing also happens when checking and unchecking the sponsored shortcuts setting.

Internet searches for Firefox support/forums shows https://www.mozilla.org/en-US/about/forums/ and https://www.mozilla.org/en-US/about/governance/policies/participation/

Searching around these links is too difficult to find where to post any questions, which happens to be on this link https://support.mozilla.org/en-US/questions/

Please make UX friendlier.

Tried to update Firefox. Got the message: your updates are being managed by your organization. I'm a home user. No organization. What is the problem? Thank you in advance.

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

I know it may sound a bit strange, but I would like to know WHY an extension is not allowed in a private window, so I might understand the reason why I'm not able to diagnose an issue I'm having with fucking amazon who has their cart all over the place for a misconfiguration in firefox that either I did or an extension is causing, however I'm unable to figure out which because I can't enable extensions in private windows, where the issue does not happen, so I'm not able to reproduce and isolate the problem. Specifically, this article: https://support.mozilla.org/en-US/kb/extensions-private-browsing Plus, I was kinda expecting I could run STG in private too, since it offer such nice and rich grouping and memory management features vanilla FF does not (PS: please take inspiration and bake it inside!!) Thanks in advance.

Hello Good People,

I noticed that the snap version of Firefox had a lag issue when typing into input field. For example, when composing an email and wanting to use backspace to quickly delete a misspelled word, then backspace works slowly, stuttering and jittering. If I hold down a key in the input field it also lays the character down in a stuttery, slow way.

I tried reinstalling the system and that solved the issue. But it has returned again. Maybe it was an update. I also installed WINE and waybridge to get some windows plugins to work on my DAW. I don't know if that has affected it.

I also tried removing the snap version and installing firefox using the terminal but the problem persisted.

It's an annoying problem. Any advice appreciated.

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

Since a while, I think it is since I created an extra testprofile with "firefox-esr -P", but I've set my main profile as default again

When opening a link in another program than firefox I get always: a popup "Close Firefox" "Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile."

I do have both firefox and firefox esr, I usually use regular firefox the second came with the debian 13 repository.

I keep the esr to test display issues for reproducibility on my personal desktop, because I manage debian 13 kiosk-style desktops with firefox-esr.

(I noticed also that the regular firefox profiles can not be opened in firefox esr, so I use an extra profile for esr)

I have HDR working in Proton games and mpv fine (using Plasma 6.4 / Wayland)

I enabled HDR in Firefox (gfx.wayland.hdr), and HDR content works in YouTube fine ( looks amazing!) however.. I have an issue in that all non HDR content doesn’t show any video (I have sound) just a green sceen (see screen shot) including all ads.

Any idea how to work round this ?

I have AMD 7800 GPU .

Cheers

I am running Linux Mint 19 and when I tried to activate the container extension some options were not selectable and a msg appeared at the top of my settings: "Your browser is being managed by your organization" I am a home user and never had anything to do with any corporate PC. The policy it lists is: disableappupdate true. Everything I see in the help database for this pblm pertains to Windows. As I said above I am running linux mint.

what is going on here???

I want to migrate everything from windows to linux, i've already synchronised browsers on both systems, but settings on linux didn't get overrided.

How can i make browser on linux exactly the same as on windows (including settingd)?

I am trying to sync Firefox data to new computer. The Mozilla account only allows me to sync mobile devices. Online instructions do no match my version of Firefox 131.0.2, Ubuntu 24.04.

In 2024-25 Microsoft Edge gained the ability to limit the usage of physical RAM that the processes uses. Once that limit is reached tabs are put to sleep or are unloaded. So a user of Microsoft Edge could restrict the memory usage to say 1GB or 2GB or 3GB and so on till the maximum available physical RAM.

Does Firefox have such an ability? Is there some flag or settings in about:config that can be enabled for a similar feature to be used? Does Firefox have ability to put tabs to sleep once SWAP is started to be used? Is there some flag or settings in about:config that can be enabled for a similar feature to be used?

If none of one of the above is not available with Firefox then will Firefox add this feature as part of the browser in the future?

I have searches from a year (or more) ago that are still popping up and I don't know why. I have done multiple clears of my entire history and individually removed old searches when they pop up - they still keep coming back.

Mint 147.0.4 64 bit I click on a pdf, it opens in qpdfview. It also saves in wherever my default save folder is. I later have to go remove all these junk PDFs from Downloads or wherever because I either didn't want them or saved them elsewhere.

Please stop "helping me". I do not want to be "helped". How can I stop this auto-save """feature"""?

I think this started back in 98.
