Firefox Community Forum

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

I used to have about 40 quick links, or bookmarks on my home page. I had pinned several. Others appeared according to how often I used them. The latest update deleted all but 3. I am very unhappy. How can I get rid of this update and bring back my quick links? I guess I will have to go back to Brave.

I teach an online Adobe Illustrator Course. Students upload (.ai) Adobe Illustrator files. Not .svg or .pdf. But Firefox changes the (.ai) extension to (.pdf) upon downloading. This is HIGHLY irritating. Firefox, in prior versions, did not do this. In Firefox settings for Applications, there isn't a choice for .ai (Adobe Illustrator) files. I 'assume' that when AI (artificial intelligence) became available is when Firefox began automatically changing (.ai) files to (.pdf). PLEASE SOLVE this as I have to manually change the (.pdf) extension BACK to (.ai) HUNDREDS of times a day.

This setting, "Always ask you where to save files," is definitely broken.

In a related article, they provided this solution: https://support.mozilla.org/en-US/que.../1534384 https://support.mozilla.org/en-US/questions/1534384]

Proposed solution: "I believe you also need to go into Tools -> Settings -> General and set the Action for the types of downloads (Applications) to Always Ask for those types you want it to."

But this workaround should not be needed. "Always ask" means always ask. As in always. No other additional steps should be needed.

Can you folks please open a bug to get this fixed? This used to work just fine in (much) older versions of Firefox and Netscape. "Always ask" is supposed to mean always ask. Like, always.

I set up my new tab (after the Home page which was Google News for my profile) to show shortcuts in four rows. Clicking on these shortcuts opened the URL for an account or webpage. I "pinned" or "dismissed' these shortcuts over time. Somehow, I lost every shortcut and cannot seem to figure out how to recreate this.

When backing up bookmarks to HTML - HTML Back-Up does not include the TOOLBAR Bookmarks. Please advise how to include the toolbar bookmarks in HTML format. Thank you.

I've tuned in to Firefox this morning to find that I'm kind of shut out, no access to my usual apps, and required to enact some difficult backing up etc. When I explore, it seems to relate to Windows 10 losing its backup from Microsoft. But I'm running Windows 11, not 10. What's going on? Is this legitimate? If so, why is it complicated and why wasn't it forewarned (by Firefox)?

This feature/option is not working. I close with multiple tabs open, and restart and only the generic search/home page is there. It is tedious to have to reopen if many tabs have been used.

I have configured Firefox to use a proxy, and I stored the credentials in the password manager. However, every time I open Firefox, it asks me to enter the credentials again.

How can I store the proxy credentials persistently?

This problem has been covered in this forum before. However, the various solutions have not worked for me because it seems my backup previous.jsonlz4 was corrupted. I did exit Firefox normally, but I am not sure because I have been using multiple different browsers in recent months.

This is what happened this morning: my Firefox on Mac OSX was closed normally, and I rebooted the MacBook. Afterwards, I could not restore old tabs because "Recently Closed Tabs" and "Recently Closed Windows" are greyed out.

I tried copying recovery.jsonlz4 from the last folder and putting it into the main folder as sessionstore.jsonlz4, then reopening Firefox. Still have no restored tabs. Here was the surprise, which I do not know how to interpret.

I just checked some files and found this error message in sessionrestore-logs folder:

1770888233416 SessionStore ERROR SessionSaver write() rejected with error: Error: SessionFile is closed(resource:///modules/sessionstore/SessionFile.sys.mjs:424:29) JS Stack trace: write@SessionFile.sys.mjs:424:29 write@SessionFile.sys.mjs:47:32 _writeState@SessionSaver.sys.mjs:375:29 _saveState@SessionSaver.sys.mjs:308:17 _saveStateAsync@SessionSaver.sys.mjs:354:10 saveStateAsyncWhenIdle@SessionSaver.sys.mjs:194:14 requestIdleCallback/<@Timer.sys.mjs:180:15 observe@AsyncShutdown.sys.mjs:570:17

I use Firefox on Windows. I like it. But I also have an HP Chromrbook and I would rather use Firefox than Chrome. But I really don't want to do the entire Linux dance. Is there an easier way to get Firefox for my HP Chromebook?

After updating to Firefox 147.0.3 all of my browser history (along with open tabs at the time of updating) is lost. I just updated to Windows 11 workstations (plus a couple of older Windows 10 workstations) to the current (Feb 2026) updates too. However the history data was lost before the Windows updates. I noticed that with the previous update of Firefox that saved login information was also lost. Who is doing your program updates, a chimp?

In the past when an update was done the browser would open back up with all of the previous versions session tabs in tact. But not now.

I've lost several tabs of research that was being done. Based on what has been happening, I will HAVE to change to some other browser. This is a shame as I've been a loyal Firefox user since day one. Good bye Mozilla and Firefox.

When Firefox updated to 147.0.3, it shredded Quick Dial and I am using the latest version.. Less than half of my tabs still exist, and many of the "everyday" tabs - banking, utilities, online purchasing, etc, - are simply gone. Unless there is a solution, and I have contacted the developer with no success, I will no longer be a Firefox user. Beyond this issue, Firefox has been increasing difficult to use for purchases (big examples, Rock Auto, PayPal) and have had to switch browsers too many times to complete purchases DESPITE making exceptions for these websites in Settings. This situation is the proverbial "last straw". Solution or I'm out. Screenshot attached would have originally shown A FULL PAGE OF TABS.

Hi,
