Using Ubuntu 24.04.3 LTS with Firefox 147.0.3 (64-bit)

Firefox crashes when trying to access any banking website. Can get to the login page, but then firefox crashes and a crash report window comes up with quit or restart option. This has been going on since shortly after upgrading from 22.04 Ubuntu. Started with Firefox 147.0.1 and after upgrading to 147.0.3 did not fix the issue.

Started Firefox in Troubleshoot Mode and that works when going to the bank login page. Using Standard Theme and only extensions Windscribe - Free Proxy and Ad Blocker and DuckDuckGo. Disabled both and same result of crashing om bank log in pages.

I run Windscribe VPN through my separate subscription, but it doesn't matter if it is on or not. Banking websites (Keybank, Kinecta, Capital Group) still crash Firefox

Also crashes when trying to access Excellus BCBS log in page. Most other websites (news, sports, Amazon) are fine.

Searches on your support page yields ) results.

Please advise!!!

The Firefox default behaviour to reload a page for view-source even when it is already in memory is unnecessary and causes many difficulties when tracking CGI bugs.

This unnecessary reloading can be turned off by setting accessibility.blockautorefresh to true.

However, fixing these stupid page reloads this way introduces another hyper-annoying behaviour: then Firefox blocks redirects.

So this accessibility setting is bad in both possible settings. Is there a possibility to prevent reloading pages for view-source while still allowing redirects?

I had 6 groups in the sidebar showing when I closed Firefox last night. Today when I opened Firefox there was only one group showing how do I get the other groups re-displayed in the sidebar? I am finding no clues when using the last line in searching help

I am unable to download large files from an MS Sharepoint account in Firefox. Small files are fine (less than 100MB). Large files download fine if I use MS Edge browser but I don't want to have to use Edge unless absolutely necessary. Using Firefox Troubleshoot mode doesn't help. Clearing the cach/cookies etc doesn't help. When downloading a 600MB file, the download repeatably fails around 90-100MB. My OS is Linux Mint xfce64. Obviously MS doesn't like firefox for some reason, even in Troubleshoot mode. thanks in advance for any help.

I'm stuck in an endless loop in Firefox for Linux (MX Linux) whenever Cloudflare is used as security.

"Performing security verification

This website uses a security service to protect against malicious bots. This page is displayed while the website verifies you are not a bot."

I click "verify you are human" and it just loops back to the very same challenge. It isn't broken in other web browsers like Vivaldi for Linux. Or Firefox in Windows 11. Just Firefox for Linux.

It has been this way for months.

I believe Firefox invited me to add another partition to my Firefox system I do not like it, finding it interferes with my normal operation of daily events and also transfers unasked from my primary partition making, for instance emails l seeking a reply.

I have a machine I've been using for months and haven't got around to archiving the history and tabs for some research I was doing. I realized this could be problematic if anything happened to the machine, so I decided to sign-in to my Mozilla/Firefox account I made years ago, so it would be safely sync'd.

Everything was fine at first, it showed it was syncing and whatnot, but then after several minutes, Firefox crashed. Upon relaunching, ALL of my history is gone! Neither signed-in nor signed-out shows any history at all, except the searches I've done just now trying to undo this mess. Did I really just loose months of history due to some bug or is there a way I can manually restore or see it from the mess of cache/profile files on my machine?

Ubuntu user, so will be at ~/ or similar for most things I assume.

Hello. I have issue with Firefox. I am often opening firefox by command: firefox --no-remote -P <profil> --new-window "<web_site>" Usualy it works. But sometimes it is opening new window and my web_site is located in second tab. First tab (which is completelly unwated) start loading after clicking on it. It is a recently closed tab. I call this tab zombie-tab. It was finished and properly closed, however it rose from the dead. I tried to set in about:config browser.sessionstore lot of parameter to absolutelly forbid to save any information. However, there is still whole history in the list, sites are restorable and sometimes it appears these zombie-tabs. Restore from crash is also deactivated. I tried before to start the firefox without --no-remote parameter, but AI recommend me to add it there. It did not help. Since it is happening occasionally, I consider it as a bug. Some my settings: browser.sessionstore.max_resumed_crashes = 0 browser.sessionstore.max_tabs_undo = 0 browser.sessionstore.max_windows_undo = 0 browser.sessionstore.resume_from_crash = 0 browser.sessionstore.cleanup.forget_closed_after = 149 Version: 140.7.0esr (64-bita) OS: Debian GNU/Linux 12 (bookworm) How to prevent to create zombie-tabs?

On my steam deck, from time to time, the firefox's touchscreen support seems to switch modes.

The symptoms are:

- Instead of scrolling, one-finger touch-and-drag now zooms in and out (depending on direction)
- The touchscreen no longer lets me select or close tabs, or focus or click in-page widgets
- This mode-switch is restricted to the firefox window in which it happens
  - Moving the tab to a new window results in the new window working fine
  - Other existing windows are unaffected (although they may later experience a touch mode switch  event)

I have yet to determine what triggers this switch, nor can I figure out how to undo it.

Listen I have a profile in another partition in Mint and want to transfer my Bookmarks/profile etc to my new 22.3 install but far too complicated. I also have a previous Key which I no longer wish to use as it has deleted all 20 years worth of messages. Please please please just set up my profile again oFirefox or then revert by to the one from 2025 Mint 21.3 Thomas McM Rbold textamos de Deus

I would like to allow or block extension for certain site.

What i need is: 1) Turn on extension on specific sites (like for government) 2) Do not load extension on specific sites

So there should be Order Allow,Deny and reverse Order Deny,Allow And two rules Deny *://example.com/* Allow *://example.com/some/*

Hi! I have a lot of tabs synced in the mozilla account on a device that I have not connected for a while (forgot it at a place far away). Recently I needed to open some of the tabs and while the device was shown in the account the tabs were not accessible. Isn't that one of the major points of using the sync, to be able to see things between the devices??? My reaction - WTF? It's like the perfect lie - hey look we have your device here.... but it is actually just the name. I am so frustrated about this.... why don't you even talk about this? Why is there no warning that my data is going away??? Why is this decision to delete the synced tabs (not the device but only its tabs) from the account happening without any notice, at a time randomly decided by someone? How is that making sense? Why can't the user be informed and make a decision? I think that's one of the reasons why you lose and lose and lose market share, because you don't care anymore about your users, you think all are idiots and you can make decisions for them and restrict their abilities to manage their experience. I know it is free software but it's getting worse until it will become absolutely irrelevant, please stop smoking whatever you're smoking and make more sense with your decisions to add/remove features and alter functionality. Just one more example of another senseless decision - the time options when I want to clear the history. Just 1/2/4h, since 12am and everything.... I am trying but there's no logic in choosing these intervals and restricting the user to only those.... Another one.... the extensions... it's like a dumb game of hide-and-seek to find their options and manage them or to put their icon on the toolbar or somewhere handy and visible so it can be used as it is supposed to be used.... does not make any sense! Ah yeah and the very very old complaint: WHY did you remove the status bar? Lots of info can be added there and it was VERY useful. This was one of the big "WTF is happening with Firefox?" moments.... only downhill from there. I will probably give up on Firefox if it doesn't come back to actually making sense. Not all users are idiots, give them back the power to use your (still good) software in the way they want, stop taking away features and options. And don't forget the power users, take their options away and they will go away.

Hi,

Since last week I am unable to properly use some websites that are failing due to CORS requests, but they were working before. Some examples are es.webuy.com or a local Jellyfin instance. After trying to enable/disable some settings that I thought could be related to the problem, like security levels, I ended up creating a new profile. In this new profile everything works, but as soon as I synchronize my Mozilla account, then these websites start failing again with CORS requests errors.

Any idea about what setting might it be the one causing problems? Or any idea about how can I debug/troubleshoot it myself?

Thanks!

Pourquoi ne pas proposer l'activation par défaut du VPN intégré au navigateur dès le lancement de Firefox ? Why not enable the browser's built-in VPN by default when Firefox launches?
