Firefox 技術支援討論區

The Add-On feature no longer works. When I click on it in the about:addons address, it just gives a paragraph of what add-ons are and the rest is just a white, blank page. Has been working just fine (several years) until just a couple days ago. I found this out when I had to re-install a couple legacy apps due to a FF foul-up (tried to upgrade even though I refused). I still use FF 55.0.3 because that is the last version that the Tabs Groups will work with. This single feature is far more helpful to me than all the other features of FF combined, so you can see why I want to keep it.

How can I get Add-Ons to actually let me add on again?

I use iCloud.com for my email. A couple days ago my launched message windows (such as opening or replying to a message) will not come forward of the main screen. The tabs appear as thumbnail previews (see attached), but will not display on top. They stay behind the main window screen and cannot be used.

I am on current Firefox version (88.0.1), and did several refreshes which would fix it temporarily, but then it reverts back. I did a complete uninstall and re-installed, but this still has not fixed the problem.

This appears to be only on this PC: I have another almost identical box where Firefox displays the iCloud tabs correctly.

I'm now having to use MS Edge to send or reply to messages from iCloud.

I use Firefox on Ubuntu 21.04 LTS and recently started facing delay of 3-4 seconds while trying to open any add-ons in top bar or even when trying to navigate application menu. I recently moved from windows to Ubuntu, no such lag or delay was there in windows.

What I tried- I tried to troubleshoot this problem with the help of troubleshooter present in Firefox and used the 'Refresh Firefox' option but still it was lagging too much. I also tried to remove all add-ons but still it was of no use. My system is fast enough to handle Firefox.

Hi,

The right-click context menu has a "open image in new tab" option with a handy keyboard shortcut, however using it one goes in to the new tab with the opened image. Is there any way to use the "open image in new tab" but staying in the current tab?

Thanks.

Hi,

I have reset mozilla sync password as was not sure which one I had there. It led to all the bookmarks and data deleted. It was my mistake and I would like to revert this password reset some way. Could anybody adivse on this please?

Thank you, Anastasiia

So basically it has been 2 days since this happened, before update 88; main page of youtube doens't load correctly (only few thumbnails) and only after refreshing it for many times; other browsers load it fine; I did everything I could find and think of, including re-installing clean install, and even restoring windows to a week ago. any ideas or help are appreciated.

MacOS Catalina 10.15.7 Firefox 88.0.1 (64-bit)

All recent Firefox versions have killer bugs.

A new one was actually trying to login here. The error message said 'Cookies must be enabled' and I couldn't get further. Cookies *were* enabled! I shut down Firefox, and re-opened, and all was then OK.

. Web pages with scripts are often completely blank. . Pop-ups are often blank. If not they often don't work, like (critically) Ebay login. . View source (CMD U) works for new pages. However doesn't update if the source page changes.

 I do use <CMD U> from the changed front page.

A silly one is that the keypress to 'Copy Link' was deviously 'A', but not shown. It has now changed to 'L' and still not shown. Why? I very much prefer Firefox, and all the many shortcuts are memorised (well bar 'L' (8-)# )

However I so often now have to use Safari or Chrome to get around the bugs. This is a pain as the interfaces are different, and specifically 'View Source' never has a shortcut key. They also have their own bugs!

Firefox will not now open in Windows 10 but opens in safe mode. When I try to open in windows 10 I keep getting error code: XUL Runner Error: Platform version "88.0.1" is not compatible with minVersion > = 88.0 maxVersion > = 88.0

and Firefox does not open.

I use three computers but one is my main computer. Is there a way to make these bookmarks my MAIN bookmarks to sync. It is annoying when I sync and my main computer bookmarks get all messed up because the other computers aren't current. I want the two other computers to sync to my main computer and not vice versa. Is there a way to set up the computers sync this way? Thank you in advance.

This glitch happens since I've started using Firefox several years ago: every time I start Firefox it extends its vertical size by adding some pixels to its top and bottom.

How can I stop it? Restore xulstore.json each time I want to restore the FF window size doesn't look like a good idea.

Attached are screenshots of xulstore.json (colored is the current and black is the backup ones) to show the glitch clearly.

I'm currently using Windows 10 Pro.

Hello, starting firefox I am always getting: Firefox is already running , but is not responding. To use Firefox, you must ........ Clicking OK doesn't change anything and there is no other Firefox running. Even newly installing Firefox ora System reboot doesn't change anything.

What can be done?

Thanks in advance for helping, Alex

I used to play RealBridge with Firefox 86 and previous versions by using a simple USB WebCam; when I udpdated Firefox to 88.0, RealBridge did not open properly the same USB2 Webcam. I had to recover back my Window 7 professional in order to obtain back the Firefox 86.01, then my USB WebCam turned back to work. Now I locked the Firefox autoupdate. I did not change any other set-up, what can I do ? I solved the problem by uninstalling Firefox and then by doing a new clean reinstall.

Recently (a few days), I have noticed that math formulas are displayed as plain Latex code in a Moodle-based course viewed on my windows Firefox browser. There is no problem with other browsers and android devices. It seems to be related to the automatic update to the version 88 of the Firefox browser. Is any one else facing this problem? Does anybody know a solution?

I'm OEMOlehana been a user of Google Chrome for recent 5 years, but I found an issue regarding RAM consuming of Chrome and sometimes the system stuck also, So I need another browser that consume Low RAM, I'm still wandering that which one will be the best choice Opera or Mozila Firefox, I need some suggestion I have already read some question and Answer on Quora related to Mozilla Firefox Vs Chrome...
