Firefox 社群討論區

One page of my online scheduling software often doesn't load all the way. It's a list of clients, not super-long. It often only loads the first 10-15 names (out of about 80). Eventually this pop-up appears: "This page is slowing down Firefox. To speed up your browser, stop this page."

I'm on a Windows 10 desktop with PLENTY of speed/memory. That's not the issue, unless Firefox isn't using the computer optimally.

I've been having tons of issues with Firefox so a few days ago I did a "Refresh." This helped, but obviously didn't fix this particular issue.

Over the past few updates, I’ve noticed an issue with Firefox where it no longer restores my previous session when reopening the browser.

I normally keep four tabs pinned and about five additional tabs open for browsing and work. In the past, I could simply click the X to close Firefox, and when I reopened it, all my tabs that are pinned and unpinned would automatically come back. Recently, this stopped happening. Now, if I close Firefox, it opens with a fresh window instead of restoring my previous tabs.

I’ve already checked the setting under General/Startup, and Open previous windows and tabs is enabled. Because of this issue, I avoid closing Firefox entirely, since rebuilding all my tabs each time has become a hassle.

Is there a way to fix this? Any suggestions would be appreciated.

Thanks :)

I cannot access the video that is available before?

Hello,

I have today encountered a reproducible issue with Firefox 145.0.2 (64-bit) on my system (CachyOS Linux). Whenever I press the "Print" button in the printing dialog for a PDF file, the browser freezes and no longer reacts to anything. I had to kill the process manually and try again. I have then downloaded the PDF and opened a different application to print it - that worked fine. Is this a known issue with Firefox? Does anyone have an idea how to fix this?

I already tried resetting the printer settings in the browser, but that did not change anything.

Thanks, Stefan

The new version of Firefox has been uploaded to my desktop withoiut any notification or communication to me. I have now lost all shortcuts and other data stored on my original Firefox, indeed, I have been taken back to the original as if I am a new user. I have used Firefox for many years. How do I retrieve all of the lost data from my old version? I am not a techie so please advise in simple step by step measures. Thank you. Regards Martin Forge

Yesterday I thought I had downloaded two CDs from Amazon Music. I received the invoices for them but could not find the downloads on my Windows 11 Desktop.

I just spoke with Amazon who said there has recently been an issue with Firefox and that I should use Chrome to receive downloads. I asked for a refund instead as I value the privacy that Firefox gives me.

I am using the latest version of Firefox and am curious to know:

1) What the issue is? 2 Have others experienced this? 3) Is it likely to be resolved? 4) Why Amazon doesn't test its software for Firefox compatibility before making changes?

Today I closed Firefox as usual. It wrote recovery.jsonlz4 and recovery.baklz4. (Sorry if I’m missing some details, I’m just a bit upset.)

On the next launch, it didn’t show a window (most likely due to gWSL). I knew that after the next exit it would rewrite the session files, so I backed up .mozilla. (At that moment I didn’t realize recovery.jsonlz4 was already overwritten.)

I killed Firefox and WSL, restarted, restored .mozilla, reopened Firefox — and it rewrote recovery.baklz4 with an empty recovery.jsonlz4. The session page showed nothing. I panicked, because my previous .mozilla backup is very old.

I found out there may be a way to recover if I don’t launch Firefox before copying recovery.baklz4 to recovery.jsonlz4. So I closed Firefox, restored .mozilla again, checked that the .baklz4 file was larger, copied it over the .jsonlz4, and opened Firefox. It successfully restored everything.

Why do I need to manually back up session files? Could they be versioned, or at least not replaced by an empty session?

If the only tab is about:sessionrestore, that usually means something went horribly wrong, and it shouldn’t overwrite the previous session.

Relying on third-party extensions doesn’t solve the problem. Replacing a valid session with a blank one leads to data loss.

As you probably understand, this isn’t the first time I’ve lost data because of this behavior. This time I managed to save it, but previously I didn’t know these steps and lost my tabs.

Using Firefox 145.0 (64-bit), "Firefox is up to date" on PC with Windows 11 Pro.

I was so pleased when Firefox's Group Tabs arrived. I often have about 12 tabs open to do Railway research. So I thought, Group Tab, great idea. Save a group of tabs as one tab. Instead of creating a Bookmark Folder and each time opening all bookmarks from said folder, what better way to do than opening one tab. Or so I thought. I also created a "SHIP" tab for my hobby in the shipping industry, so I could have two group tabs that could be collapsed making the tab bar tidier. I saved an closed each group tab then closed down my PC. Next on restarting, Firefox starts up automatically as chosen by me. Both RAIL & SHIP tabs reappeared without me doing anything. Great! However yesterday, I inadvertently opened another Firefox window, forgot it was opened. So when I shut down my PC, I closed the Firefox browser and then discovered the over Firefox window I had opened. Closed it shut down my computer. Of course when I opened my PC today, Firefox started automatically, but with the tab that I had open in the last Firefox window. No problem I thought, I will just open the saved Group Tabs. It was a problem, where are the Group Tabs saved? Could I find the location? NO! I looked in Bookmarks, all the various History lists, even the down arrow to list all tabs. Nothing, the Group Tabs are none existent. I have checked on the "about:config" section for Group Tabs and everything is enabled "true". So where are the Group Tabs saved? I have been with Firefox for around 14 years, often citing it as the best browser. But over the last five years I find myself using Chrome more and more. Chrome has Group Tabs which do not not need the users to save them, they are saved automatically, and are easily found on opening the Chrome browser. Why doesn't Firefox have this?

Just updated my Firefox. I had a huge tab group saved, and tons of bookmarks. I've been using firefox for months, I didn't have an account signed in on the browser though. I updated it and it had to restart, and everything was gone when it reopened. I even clicked that it should reopen tabs after restarting, but it just opened to tell me to make a profile. It told me that they just introduced profiles, and it put me on profile 1, which looked brand new. No browsing history whatsoever, no bookmarks, my background that I set is gone, and I cannot find anythign at all. I had over 50 bookmarks, inclyding very imprtant links for a final paper, and I'm genuinely so upset. Multiple of those bookmarks were things for me to go back to read/watch later and I will literally not be able to find them. If anyone has any tips at all, I'd love them. I am so seriously upset right now and I'm just hoping its possible for that to come back.

latest version of firefox will not let me save a password on a new website, it has always worked before, see image for settings. website is not included in exceptions

how can i force the active tab to show? i am fairly sure this feature was in a previous edition. I have a large number of tabs and sometimes an app or video will start and i am forced to go back and forth thru all the tabs just so i can stop them.

My browser stopped loading certain pages, like Instagram, Facebook, and Amazon. Caches are cleared, extensions are disabled, tried service mode. Other browsers seem to have no problem loading these sites. What can be the problem?
