My question is above!

I had a free chatGPT on firefox sidebar. you changed it to Anthropic Claude without my permission. Now I have to pay for something I was getting free as a student of a university.

How can I restore the FREE ITEM AND GET RID OF SOMETHING I WILL HAVE TO PAY FOR...AND STILL USE ai?

I've used Slack every day for the past decade, and Firefox has been my primary browser for some time now. I've never had an issue with the two, but now, Firefox is reliably crashing every time I attempt to open Slack.

I've tried clearing my cache both broadly and specific to Slack, with neither producing results. Even tried deleting all cookies on Firefox, which was a bit of a pain, and it was no help.

I did read up on some people encountering a similar issue that could be fixed by deleting the Slack entry in "about:serviceworkers," but this did not help here.

The only extension I'm running is uBlock Origin, which I've been running for probably as long as I've been using Firefox, and that has never presented an issue before either.

Would appreciate any help or advice on the matter.

Firefox updated to the latest version and it lost everything. All my saved passwords are gone, all my bookmarks, data, etc. It said I could sign in with my account and it would sync them and bring them all over, it didn't. I can't use the original profile because it says it's outdated, I don't even know if it's the correct profile anyway. What am I supposed to do?

Using firefox 144 on Kubuntu 24 LTS, on wayland, with Nvidia drivers.

I'm one of those guys with 500+ tabs. I also have a bunch of tabs open in specific containers and I recently spent a lot of time sorting most of my hundreds of tabs into a bunch of neat tab groups.

I'm not using any "sync between devices" functionnality

At some point, I open firefox like usual, and I noticed that it appears to be glitched. The rightmost tab (the last tab I had opened) seems to be working fine, but every other tab has no text, and I cannot switch to them. However, the colored line indicating that a tab is opened in a specific container still appears, it's just the tabs names that are missing. Also, firefox seems to generally not be responding, so I decide to close and reopen it.

Upon reopening, firefox restores my tabs, but I'm left with only the last tab I mentionned earlier. The "restore last session" button doesn't appear in "history". Neither "recently closed windows" nor "recently closed tabs" contain my 500+ tabs

I still have my extensions

I still have my bookmarks

I still have my base "new tab" setup, with my background image and my "pinned" websites (I don't know how it's called)

I still have my container "rules" (i.e, firefox still proposes to open specific domains with specific containers, even if I have lost old tabs that were opened in those containers)

I still have my "auto sign-ins" (i.e, I can still log into some websites without re-typing my password)

I have lost my tab groups

I'm used to losing my tabs. So I close firefox, and I go look in it's files.

The image firefox-mpris in the files still displays a youtube tab I was watching (yet this tab doesn't get restored)

I make a copy of sessionstore.jsonlz4 and sessionstore-backup, and try restoring from each backup by replacing sessionstore.jsonlz4 :

- the default sessionstore.jsonlz4 doesn't have my tabs of course

- previous.jsonlz4 has only the single last tab I mentionned earlier.

- recovery.jsonlz4 contains only 20-ish of some of the most recent tabs I had

- the "upgrade" files contains a bunch of tabs but it's from a few months ago so I'm missing the most recent stuff

Using this "scrounger" tool, I can look at what these files contain

https://www.jeffersonscher.com/ffu/scrounger.html

- sessionstore.jsonlz4 and previous.jsonlz4 both contain the single tab we talked about before (plus closed windows I don't care about)

- recovery.jsonlz4 contains exactly 25 recently opened tabs (plus closed windows I don't care about)

- upgrade.jsonlz4 contains 500+ tabs (with container ids, yay), but not the most recent ones of course (plus closed windows I don't care about)

From I saw online it looks like firefox only stores the last 25 tabs in these files, which are the last tabs I actually opened, even if more actually exist. What I really don't understand is : - Why does my upgrade.jsonlz4 file have more than 25 tabs then ? - Where are the other tabs supposed to be stored then ? the .jsonlz4 stores the last 25 tabs, yet firefox (usually) remembers all my 500+ tabs anyway, so where are they stored ?

Also, y'know, pls help me restore my stuff. Thanks.

I was interested in seeing how the profiles worked so I clicked yes to creating one, but once I set another one up I realised I would have to use a separate Mozilla account on it and I would prefer to keep everything on one browser and account. I tried to delete the profiles but it said it would delete all my bookmarks and data, is there any other way to hit undo or something and go back to the way it was before (without profiles)?

I'm trying to stop Firefox from restoring tabs after I restart my OS. So far, I've done the following:

• Disabled `Startup > Open Previous Windows and Tabs`
• Disabled all extensions
• Confirmed I do not have a `user.js` file
• Set `browser.sessionstore.resume_from_crash` to `false`
• Set `browser.sessionstore.restore_on_demand` to `false`
• Set `browser.sessionstore.resuming_after_os_restart` to `false` (It was already set this way.)
• Set `browser.sessionstore.max_resumed_crashes` to `0`
• Set `privacy.clearOnShutdown.openWindows` to `true`
• Set `browser.sessionstore.max_tabs_undo` to `0`
• Set `browser.sessionstore.max_windows_undo` to `0`

(I've since reverted the last two and the extension changes after they didn't work.)

So far, Firefox will not restore tabs on application restart (manually closing and relaunching) or on crashing (after sending SIGTERM/SIGKILL), but it still restores tabs after restarting the OS (if I allow the OS to kill it during shutdown). I've seen a couple suggestions to disable history completely, but I do occasionally refer to my browsing history, so I'd prefer a less-drastic approach. Ideally, I just want Firefox to treat the first launch after a shutdown as a normal launch and not apply any special behavior. Any help would be much appreciated!

Windows 10, latest version.

I hit a shortcut, I think, and heard the trackpad, then one of the three open tabs was isolated from the rest in a separate, almost chromeless window.

It's not in the taskbar pop-ups but instead has its own icon. In this 'chromeless' window there is no option to add a tab or window, there is no area to move it (I have to carefully use emtpy space in between buttons to move it). The top just fell off, that's basically it.

I have never seen this and have been using Firefox from the start way back when. I didn't install anything; this just happened as I was reading something and accidentally touched a key. Nothing changed, no settings were adjusted, nothing.

This option is not in the tabs menu or anywhere. I must say I kinda like it for this one 'tab' (which is a solo chromeless window) but I do need the menu and so on for productivity.

One of the screenshots shows this 'window', the other shows that 'window' is not part of the regular pop-up tabs in the taskbar but rather has its own icon, as if it were an app, in that taskbar.

What in the world is this? Can someone help?

Mozilla sidebar has been replaced by "Choose an AI chatbot to use in the Firefox sidebar." How do I undo this and return to Mozilla standard Firefox sidebar. Not at all what I want to do. Help

I use McAfee as my security system. They recommend going to Firefox settings and disallowing random site connections. How do I get my system running again.

Уже больше недели многие сайты не открываются на Firefox, а некоторые открываются некорректно. Другие браузеры работают нормально. Хоть отказывайся от Лисы, как от основного браузера

Laptop running Windows 10 pro. Firefox 144. Is there a method for sorting firefox bookmarks into alphabetical order (yet)? I see from questions asked years ago that Firefox hasn't had a way to sort all bookmarks into alphabetical order in one go. Is this still the case? It seems hard to believe that the only way to do this is to sort each folder individually. I noticed that I can do this (and have done) on Android, but not on the laptop.

(If any relevance, I'm on Macos 12 Monterey) 'Installation and updates' seemed the nearest topic due to the 'update' part of it, since this seems to only have been happening since this version, or I have simply not noticed due to not having needed to know. But if you look at my two screenshots, you will see the issue. There simply is no About Firefox on my firefox. Neither directly listed on the menu, nor as part of the 'help' sub menu.

Is there, for the sake of learning, a simple fix, so that I donlt have to uninstall/re-install? or an 'about config' type fix? Screenshot 1 shows the menu Screenshot 2 shows help sub-menu As you can see, absolutely no About Firefox

And, only potential issue may be, as you'll see from the share data upload is that I've a lot of tabs open, as I've got a lot to get through toniught, and tomorrow. So, maybe, t=though doubtfully, it is because it isn't handling the tabs and this caused a menu entry to be missing? Surely not likely.

Hello, I'm having a problem on Windows 10. It's a fresh windows installation and I tried already some solutions: reinstalling firefox, deleting cache, refreshing firefox, private windows, no add ons, trouble shoot mod. Nothing helped. The problem seems to be with live stream, either on twitch.tv or youtube.

Unsure if it really matters, for now, but my firefox account, when I go to edit bits and pieces, it gets my Firefox version correct, but gets my MacOs version wrong. I'm on 12.76 (Monterey), but Firefox is showing me as 10. Is this normal or anything that might matter?

And a screenshot below just for those, like me who, prefer a book for it's pictures
