Firefox 技術支援討論區

Suddenly on my PC the icon of Firefox turned white on both desktop and taskbar. And whenever I try to open Firefox, it says, "The file or directory is corrupted and unreadable." And I didn't make any changes myself. So far it was fine. Now what can/should I do?

Unable to run firefox. I get the error message. (see attached screenshot) After terminating firefox processes, I attempted to create a new profile. and see an error message. (see attached screenshot)

Sometimes all add-ons / extensions break randomly and are disabled (the icon of the extensions is also broken under "Manage Your Extensions").

The extensions are visible under "about:addons", but the slider is turned off and the icon in front of each extension is broken / empty.

It seems that deleting these 2 files- compatibility.ini and extensions.json inside the firefox profile folder, usually fixes the issue. Only these 2 files though, don't delete anything else.

No need to mess around with the ff profiles or anything else, just deleting those 2 files and restarting the firefox usually fixes the issue with the "unregistered" addons.

This thread is for the search function, as I found some VERY old and outdated suggestions for the aforementioned issue using the search function.

I wonder what causes the extensions to "unregister" randomly.

I realized since I upgraded my MacMini to 14.4.1 I can no longer 'post' into any of the yard sale/garage sale sites I am on, not even MarketPlace. All I get after a long wait is a 'technical problem' notice. Am I doing something wrong?

in the firefox browser is there any way to see the casting the browser screen to chromecast on tv. similar to 'cast to media device' in edge browser or chrome browser.

I find it very difficult using Awsome screenshot, in fact I never use it, but used to use it, when it was on my tool bar, can I get it back there.

I cannot drag it from "customise tool bar" as it does not show there, it shows in my list of add ons, I have tried removing it, then reinstalling it.

I have 3 laptops all running windows 10 or 11. These all share a docking station giving access to an extended display, keyboard etc. All laptops run fine with the docking station except for one issue with the newest laptop... The screen resolution, only on firefox on the one laptop, (everything else is fine) is completly out of whack. I have tried the zoom function but no luck. I have trawled the internet but all the solutions are from 10+ years ago and refer to different versions of firefox and windows. I am not a computer geek so please dumb down any advice.

remove ad blockers even though I already have removed them.

printer is not recognized as being online although my other devices don't have the problem. i use Firefox on all devices

Hello,

 One of my email accounts Yahoo or Gmail appears to have been hacked. I received two phishing emails this week --3 if you count the last one who said she was calling on behalf of Medicare/Social Security and All members could get a preloaded card for several hundred dollars. I knew there was a plan to help certain folks, but it was not available to everybody. I asked her for the name of the plan and she hung up. the webpage she sent me to first or told me to go there where I could talk to a licensed agent. Do people who answer the phone have a license like insurance salespeople? Anyway, they had copied the govt. the site is right up the US sea.

Okay, just an example so I decided to try that KeeopassXC program you were offering but I could never get it to complete.

but it did something as I can't use my password They cancel your account if you tell them the truth --better just to say I need help resetting my password. They then ask you to send them a picture ID as in Driver's License. Noway I am going to do this --so I have at least some pretty valuable info if I can't get in.

Ny first time writing here - if any response please direct suggestions to pke225x2gmail or I guess I will check here. Don't know how you put people with possible solutions to seeker of HELP.

Sincere Thanks Paul

Hi - I can't get 'pocket recommends' stories to appear in FF on my macbookpro (14.4.1)

I've done pretty much everything I can find online including the below – nothing works

ANy ideas?

Type "about:config" in the address bar and press Enter Click "I accept the risk!" to proceed In the search bar, type "browser.newtabpage.activity-stream.feeds.topsites" and press Enter Right-click on the "browser.newtabpage.activity-stream.feeds.topsites" preference and select "Reset" Restart Firefox and open a new tab to see if the Pocket Discover tiles appear.

Whenever I get a link whether in an email from a verified sender or from using a site like Amazon, clicking on a link always results in "Hmm. We’re having trouble finding that site." This has happened ever since loading the most recent version of Firefox (124.0.2) and it is very, very frustrating. What is causing this? Even in "safe" mode this occurs. Please rectify this situation. I do not want to have to change browsers after more than 20 years with Firefox.

Hi,

There many extensions such as:

https://addons.mozilla.org/en-US/firefox/addon/search-on-imdb-context-menu/ that say when trying to install:

Installation aborted because the add-on appears to be corrupt.

I am using Firefox Developper Edition, with extensions.langpacks.signatures.required set to false.

This addon, after download, installs fine as a temporary addon.

How can I install it permanently?

Thanks.

On the page listing passwords, it was possible to sort them by "Alerts".

In settings, there is an option to enable checking the vulnerable passwords: https://support.mozilla.org/en-US/kb/firefox-password-manager-alerts-breached-websites

On my other laptop using Firefox v121, the alerts are properly displayed. But on my second laptop using Firefox v124, the alerts are gone. I can't sort password by "Alerts", the option isn't there. Both laptops share the same Firefox account and have password synchronized between each other.

Obviously, I ticked the "Show alerts about passwords for breached websites" box in the settings but it looks like it does not nothing. I also checked in "about:config" and everything seems good.

Is this feature gone?

Recent issue, April 2024. Had version 124 Firefox on Win10 computer and went to Help - > About to have Firefox check for updates. This has worked just fine up until now. The message "Failed to check for updates." is shown in the About screen. I have uninstalled and re-installed Firefox with the same results. Have also un-installed Firefox, un-installed Mozilla Maintenance, then removed Firefox data from App Data folder in user directory, then re-installed with the same results. Also, now when I access a local media server, I keep getting the message "Firefox is installing components needed" and that never goes away. Any ideas?

The RAM usage increases, from 1GB to 40GB+ within a matter of minutes of starting Firefox. I have not added any extensions in months. I turned of several with no improvement. I have 6 tabs opened. Firefox has crashed several times the past couple fo months. I have been away on travel for 2 weeks, and today the problem is much worse.

Firefox (37916) 51GB, Extensions (34308) 370MB, GPU (33072) 298MB , and everything else < 100 MB.

I really love Firefox - use across my 4 devices. Only on my desktop am I seeing this. Laptop, iPad, and Android all work fine. Running Win 11

Hello everyone,

Why some Wikipedia pages cannot activate reading mode under Debian 12 and Firefox ESR 115.9.1, for example this English Wikipedia page on Emmabuntüs does not allow reading mode to be activated while French, Spanish and German pages can ?

See our test video on this subject: http://share.emmabuntus.org/Accessibility/Firefox_mode_lecture_non_disponible_emmabuntus_en.mp4

Is there a utility to test pages compatible with reading mode?

Or otherwise in which Firefox log file to see if a page is compatible or not?

Thanks in advance for your help.

Hi, i just got a new laptop (Asus Zephryus G16, 2560 x 1600 screen) and after installing Firefox there is a thin white border to the left of the screen when running in fit screen. This problem is not present when in a windowed mode or in F11 full screen.

I tried updating the Intel Arc drivers but this did not fix the problem. Changing to compatibility mode also did not fix te problem.

PS: in the uploaded screenshots it is quite dificult to see the white line(because the background is also white), but when the image is viewed in a new tab it is visible.

Thanks
