Firefox 技術支援討論區

Today, after I tried to uninstall some mouse drivers leading to a freeze and reboot, my firefox upon starting lost hundreds of open tabs I had, only restoring 1 tab which I am pretty sure I did not even have open. I have already followed solutions in similar problems like this (https://support.mozilla.org/en-US/questions/1310742), which did not work. First I used shadowexplorer to recover sessionstorebackup files from a restore point on 10/15, most of which did not seem to open anything when using them with the scrounger tool. One of them did open, however it only showed 2 tabs when I would have had hundreds. None of these files did anything when I renamed them to sessionstore.jsonlz4 and placed them in the appropriate folder, even if I deleted the original sessionstore file. Firefox also seemed to be able to recover tabs which I opened after the loss of the original tabs, and renaming and replacing of the sessionstore file until I tried deleting the entire sessionstore backups folder.

I also tried simply doing a system restore back to 10/15, which also failed to help. After doing a system restore, I also tried the whole process of recovering sessionstore backup files and replacing them again, however nothing changed again. I also tried recovering the sessionstore.jsonlz4 file directly and using that to replace my current sessionstore.jsonlz4 file, but that also did not work. The replacement files do seem to contain tabs, as most of them are around a couple MBs large, but after I place them in and restart firefox they get reduced in size back to almost nothing.

The only thing I have not tried is using files from an even older restore point on 10/12, although after having restored to the 10/15 point my 10/12 restore point seems to have disappeared. I can try undoing the restore in order to try to view the 10/12 restore point again, but this process takes multiple hours and I would rather not.

How to Advise Mozilla that Capricious Changes to FireFox Interface are Unwelcome!

Perhaps some like change for its own sake. Many just want to use a browser to get work done.

I am Reticent to Upgrade FireFox because I now expect something To Change, To Break, I don't want the look and feel to change when I want to get work done! I want security fixes but broken features and a rearranged interface hinders the use of a browser.

Continuity is key to smooth use of a Browser. Moving menus, changing tabs, rearranging features, dumbing down menu titles is most unwelcome.

I particularly don't want browser interface changes intended for a tablet or pad for use on a desktop or laptop computer.

Changes to the Appearance should be OPT IN not OPT OUT.

Sometimes rearranging/detaching tabs no longer works. I have restarted my browser in troubleshoot mode and the issue persists. I would like to help while I'm currently in this state if at all possible.

Version: 93.0 Windows version: 10 21H1 (though this has existed before this one as well) browser.tabs.allowTabDetach is true

I have Only one Firefox window opened, in that window there are lot of tabs, I need a way to close a specific tab by title or Url from command line, something like: close_tab_command https://www.olx.com.pk

Dear Mozilla Support,

After some update (I think from 89.0.0 version of Mozilla Firefox - this version with new looks of tabs) I notice flickering on the tab when I loading website or refresh website. This looks very strange. Like I said I dindn't notice any issue with flickering on previous Mozilla Firefox versions. Only with these new versions with new look of the tabs. I didn't remember if it was 89.0.0 version or 90.0.0 version. I don't know if it is problem with the machine but I didn't notice this issue on another computer with 90.0.2 Firefox version but with Windows 10 OS. I also noticed this issue with Firefox 90.0.0.2 with Windows 7 OS on another computer so I don't know if this is problem with two computers or Firefox itself. Can you help me?

Yours faithfully, Piotr

A firefox window crashed. Luckily I am able to get back into it using ctrl+shift+n. However, when it reopens, it doesn't open fullscreen but minimised and when I try to make it fullscreen, the left and right arrows to maneuver through the tabs at the top are gone, and I can't click past a certain amount of tabs.

if i can get a multiple mini screen on One desktop, on couple of video's with voice and state bar access control it will be great. i will built UP s multimedia Wall'

I truly cannot fathom why a browser, in this day & age, cannot put the list of open tabs & windows in the drop-down menu, in even SOME KIND OF ORDER! But no, it's nothing more than a long list, impossible to filter in any way, that is not in chronological, alphabetical, order of most recent used, no option to list via website or page title, etc. This is so ridiculously frustrating, along with the molasses lack of speed in opening up windows or tabs, that I'm on the verge of just chucking this entire app, for good. Why do our state-of-the-art advanced technological devices and apps, feel more like we're going backwards, and not forward??

[Win 10] A few days ago something happened with Firefox. A message appeared saying "sorry - error". Anyway, I had to rebuild the whole thing. But, the little house symbol for the Homepage Tab is missing. It isn't even available where the choices for Menu Bar appear. I did not cause this problem. My older pc, also Win 10 is perfectly O.K. Any "Help" just brings me back to the older information from 2011.

I set "Open links in tabs instead of new windows" and it opens the bookmark link in a new tab in W10. It opens the bookmark link in the current tab in W11. Both are v93.

My preference would be the W10 way.

Not sure why this would be an OS related issue but there we are.

In the current version of Firefox, if (which is very rare) I go and open more than 17 tabs, some go off the one end of the top of the screen, and I must scroll over to find them. If I remember, on a very old version it was either 15 or 11 tabs before that happened.

Is there a way for me to change the 'limit number of tabs before they go off the end'? I would rather like to do that, but I have not found how. I would be most grateful if you can help.

Thanks,

Peter

Video: MSI 3070 X3

System Drive: 250GB fast Samsung SSD, with 50% free.

System OS: W10Pro_x64 21H1, Defender, no Firewall, no extra AV. Firefox_93.0_x64

Network: TYPE: Dedicated FIBER LAN Provider: Telenet Account Type: FIBER_200 Plus +

Addons: Adblock + µblock FBPurity Block Sender New Tab Override Cookie Manager and Cookie quick Manager Auto-High-Quality for youtube Ant Downloader Video Downloadhelper Cute Save Button WebP Image Converter Translate Web Page

Additional Information: Open Pinned Tabs: In between 25 and 60, depending on my current activities.

Tried: Disabling each add-on until all were off. Safe Start. Nothing helps.

Understandings: 1) No browser is made to run up to 60 open tabs (possibly even more)!!! 2) I run a "plethora" (compared to most users) if add-ons; these also bring the use speed down. 3) Resource used: 2GB (with "mere 30 pages" open.

BUT: DESPITE that: I ALSO understand that, considering my system and Network Type, it should not even be problematic with 200 pages open at once. 2GB over 32GB of RAM? Not the slightest issue (and it often runs at 4GB RAM in use). My CPU never runs half high, even when I have like 60 pages open: Should not be an issue then either. My Video Card has plenty resource over as well when at highest for me usage." Again, it should be no issue. My Fiber Netware? Telenet BVBA, Mechelen Test results: Ping: 5ms Jitter: 2ms Download: 904.2 Mbps Upload: 038.3 Mbps Not the best, not the worst, but for simple browsing, more than, I would assume, plenty.

So, what gives, what is the issue? No extreme strain on the system, no background high-resource issues, sure: one or two add-ons in Firefox but these as well do not strain my system, no AV issues, no Firewall issues (I turned that off, I fail to get the need for one as a house-dog-tree user), yet slow performance. Also, while 30'ish tabs running, 2GB used of RAM? My my, what the hell do they do as Site Admins to have these amounts (and NO, I do not do porn, thank you.  :P I am well aware of other people having insane issues surfing porn, as I helped many of these folks)? Sure, Deviant is a larger one that is open, being a graphical site, but like Quora, FB, Hot- and G-Mail and similar, these ain't, so to get a 2GB usage is weird, I would assume. I said, assume: yes, I am not specifically an internet know-all, I know of networking as a former NOVEL Netware Supervisor under UNIX (also Spupervisor), but Networking in a company is not the same as internet.

So, what is going on, why is my browser so slow? Having turned of all and 1 page open it's lightning fast, but now ... So, it is the open tabs, and the add-ons, though when turned off, I see no real difference. Brings it to tabs. How come, it is this "heavy", even for my system, please?

Thank you. Xog.

If I assign a certain site to a container and close and reopen Firefox, the site still loads but is not assigned to the container anymore. It only does when I set a site to always open in a specific container. Is it supposed work like this, or can I change this somehow? It is fairly inconvinient if I have to reassign every site to the right container every time I start Firefox. Thanks in advance.

Hello. My Firefox (PC) has just updated to version 93.0. The problem now is that whenever I open a new tab, it is in dark mode, and the entire page is black. Only the address bar is white and visible. I have New Tab Overide, and each new tab should open the Google home page. So something is going on... I have never set dark mode as a preference for Firefox or Windows. Thanks to whoever can help me. Florio

Recently after the last update I lost all the tabs and also the possibility to recover them through "restore recently closed windows", as it wasn't clickable anymore all of a sudden. Moving files in the firefox profile folder isn't making any difference, perhaps I'm not doing it correctly. Anyway I only have files from the day in which I lost everything, so nothing from days earlier as it seems. Please help, the tabs vanished all by themselves, I didn't have a role in it, though I absolutely need to get them back

With recent versions of Firefox, I haven't found how to open all tabs from another synced computer. They use to be displayed in bookmarks or history lateral menu and I could use the right button to open all. If this option has been removed, I don't understand why going steps back.

Hiya I want to be warned when quitting multiple tabs BUT I do not want the session restored when opening again. This used to be possible but now in Settings if I untick Restore previous session even though Warn you when quitting the browser is ticked it does not give a warning when I quit Firefox. So this means if its unticked then if I accidently hit the close button I loose all the open tabs in firefox. If ticked I have to close all the tabs manually each time I close firefox to prevent thm opening when I start Firefox again. Im on Windows 10 Pro 21H1 with Firefox 93.0 any idea if I can change this behaviour in the advanced prefs? (about:config) thanks for any insights A
