Diễn đàn hỗ trợ Firefox

Let’s say I have 20 tabs open, which I don’t quite remember anymore but occasionally return to. Naturally, I have the browser set to restore all tabs on startup. At some point, for one reason or another, a second browser window opens in the background. I close my main browser window, and I’m left with just this second window. When I close that one too and then reopen the browser, I no longer see my 20 tabs — I only see that second window with a single tab. In the Firefox View menu, I don’t see my 20 tabs in the list of recently closed tabs or in the list of open tabs. Is this expected behavior? Are there any plans to fix this?

I couldn't find a place to discuss topics regarding Bugzilla itself, so I'm looking in this community. If there's a better place, please tell me.

The title is pretty self explaining. I submitted a bug report on Bugzilla and I want to edit my bug description. How can I do that? I didn't find a way to do that. Maybe I'm overlooking something.

If there's actually no way to edit your bug description and comments, then I think Bugzilla is even more trash than I already thought it is. In my opinion that's standard and it should be supported, just like it is supported on proper tools like GitHub. I don't like Bugzilla because it doesn't look as clear and modern as GitHub or GitLab, has a worse text/markdown editor and it seems to be lacking some useful features. It's good that Mozilla creates some competition to big tech companies but it's also valid to criticize their products if they are simply worse (which is disappointing but nonetheless, it's true sometimes).

Mozilla Firefox constantly not responding. I have been unable to access any of my sites, as the browser doesn't seem to be working. Very frustrating. How can I refresh Firefox to reset it??

I have accumulated a LOT of bookmarks over the years. I want to streamline it and delete several so I have room to add more but it will not delete them. How do I go about deleting the bookmarks I want and adding more that I do want? It's very frustrating

Lately, whenever I try to open a PDF from a website open in Firefox, the tab crashes and the PDF does not open. An error stating that the Windows file-dialog has crashed is displayed at the top of the tab. I tried to attach a screenshot of the error but that action only generates another error.

This condition does not occur when I try to open the same PDF from the same website open in either Chrome or Edge, the PDF opens properly which leads me to believe the problem is in Firefox and not my Adobe installation.

Thank you

This is the link. I can't send animated images as the text is too small, so I'll describe it instead. It's so hard as a loyal fan, I'm crying.https://www.bilibili.com/bold text。There is a bug. Why does the Bilibili website not display the corresponding screen when I try to move to it? Speed playback cannot be used at all, and there’s also the issue of not being able to use fullscreen on Firefox. Are you forcing me to use another browser?

Since adding the recent updates for Mozilla my Bookmarks menu which was on the left side is gone. Using F10 or Ctrl does not work. Please tell me how to get it back to the left side of the screen

Today my Firefox browser updated & all my bookmarks have disappeared. In place of my Bookmark toolbar is just "For quick access, placeyour bookmarks here on the bookmarks toolbar. Manage bookmarks(link). The bookmarks side bar is empty. I've followed the instructions to try to recover them but the page(Goes there from the "Manage Bookmarks" link) they send me to has no functionality. Whatever I enter goes nowhere, whatever I select. I've tried several different routes from the support/help pages to resolve but always end up at this dumb page. See here(https://www.dropbox.com/scl/fi/fop0kf0qb2nu442pqc6jz/Screenshot-2025-05-14-17.13.28.png?rlkey=3x1pchkfxq12whipytzzkte2x&dl=0)

How do I get my bookmarks back when the tools to do so don't seem to want to work?

When i upgraded Firefox my old profile doesn't show up now. I found my old profile under about:profiles but when i click on the Launch profile in new browser i get this message, "You've launched an older version of Firefox. Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox" I did create a new profile but how do i get my old saved data, add ons etc to the new profile?

I cannot make fire fox work at all.for me. I need the file, edit, history, bookmark tool bar back. I'm pleading with you. Please I BEG you to uninstall the upgrade. Please let me have the Firefox I had last week. I,m 88 and will die before I ever!!!! i can't make anything work.I have over 5,000 bookmarks. I write for a few dollars to partly support myself. Right now I'm out of business. Where is the invisible email address? I have been using FIREFOX since it came out. i can't go through your circus. A browser should have a high degree of instinctive coordination, it shouldn't be similar to experts cryptic calculus level, when your totally unfamiliar with the level of calculus I'm sorry, I won't be able jump through hoops..

When I'm trying to use critical services here in Sweden,I just experience bad compatibility. In wich is the same as if they don't work.

Since that many goverment services nowdays only communicate with Swedish citizens. But hower I could use this services in the past ( in older versions).

What's not working is: 1.Skatteverket.se ( Swedish local tax agency) 2.Kronofogden.se ( Swedish bailiff agency) 3.Minmyndighetspost.se ( Swedens offical goverment mailbox,administrated buy skatteverket)

What all this services have in common a service called CGI. However since all of this services is depending on BankID( www.bankid.com). So I don't whenever there is some conflict between BankID,or some security conflict ( related to security patches).

I also know whenever my local cookie setting may affect. Since I'm in Icognito mode - and set Custom Cookie settings ( disable 3: rd party cookies). However I could use this services with the same settings without any issues.

Since I've also have updated,because my bank didn't support older versons. Anyway it's still the same.
