Firefox 技術支援討論區

On one computer I have deleted everything from Firefox including the folders within Apps Roaming except for one folder. There in one folder "41A66E7EE5E1" within Profiles which I cannot delete. It holds the files prefs.js and sessionCheckpoints.json which were created at 20/02/2021 and I cannot delete those.

My new installation is dated 24/07/2021.

There is nothing in the properties of those two files to suggest an issue. I do find however that when I seek to change the Property/Security to Administrator (I should be able to do that) I receive a dialog box that "the file or directory is corrupted and unreadable".

Please advise on how I address this.

Hi. Previously I installed Firefox on Ubuntu with command `sudo apt install firefox`. I'm using Firefox 88.0 for Ubuntu. I want to update it to the latest version. When I try following commands: `sudo apt update` `sudo apt install firefox`

It says "firefox is already the newest version (88.0+build2-0ubuntu0.20.04.1)." But I know version 89 and 90 are released.

I attached "About Firefox" window. There is no update button.

My install of Firefox was somehow corrupted. I was instructed by FF tech support to download the latest "Nightly" build, extract it to my "Downloads" folder, and launch it using the following command:

MOZ_ACCELERATED=0 MOZ_WEBRENDER=0 ~/Downloads/firefox/firefox

This opens a working install of "Nightly" (with purple & blue firefox icon), but as soon as I close it, the icon goes away. The program is not recognized as "installed" so it does not appear in a search for installed apps. And if I right-click on its icon while running, "Pin to taskbar" is not an option.

"Nighly" is working (I'm using it to type this) and I even have it Synced to my account, but the ONLY way to launch it is via the Terminal CLI. :(

My broken copy of "Firefox" is still listed as installed, but is unusable.

HELP! TIA

I have an old PC desktop which I would like to replace with a newer model. I want to get a used one with Windows 7 on it. I know Windows 7 is no longer supported but I have a lot of old software that I use, some not often, and have no desire to purchase new software. I was told that I could not download Firefox onto a newer PC with Windows 7. Is this true? I do have a laptop with Windows 10 that I use for on line ordering, etc. I like the desktop as it has a decent keyboard and mouse.

I already use FF on my current laptop. I need to put on my new laptop WIN 10 . I want to make sure I get all settings,ext and MOST imp all my bookmarks. I have read about PROFILES etc and do not have enough confidence to follow instructions. Can I just install FF on my new laptop and sign in and retrieve all the above mentioned esp my bookmarks?

Attempting to patch a corporate template (reason why the version is so old) and when using any later ESR installer with the -ms parameters the old version remains.

The installer returns a 0 exit code when done through our scripting. However it never actually installs.

Being ESR there are no logs.

When you manually install everything goes fine. The scripting handles elevating permissions, we use the same functionality across the enterprise so we know this should not be the issue.

However, and this is the odd part, if we "inject" a new installer in our scripting it will install if done without any other actions. However, for production support we have many other third party app updates.

I was leaning towards app conflicts (maybe handle locks on required libs etc) but after much testing, there are no conflicts.

I am at a loss. Any thoughts?

Not for the first time, but now on a brand new computer, I suddenly cannot download any files in firefox (from PDFs to wetransfer links etc.). I have followed all the online advice there is. In troubleshoot mode I can download files. However by a process of elimination it is not caused by hardware acceleration, addons or extensions or my avast antivirus. This is really troublesome and I really need to download alot for work.

Please advise ar

i got a new browser, was trying to get it to recognize mailto commands. instead it opens a window to go to a profile (tried it in edge does the same thing).

originally it was finding an old profile i made ages ago, but it insists on making a brand new profile.

the thing is, i don't have a profile, all my files are listed in a custom directory i put into the thunderbird directory (to make it portable). and if i try to make a profile it blanks it all out - settings, structure etc. even if i copied the old files into a new directory and focused the new profile with the old files in it.

and now i'm starting to confuse myself.

basically i think what i need is - the ability to create a profile of my current settings, so i can give that to the browsers. i don't remember having this issue with waterfox. but i'm using something else now. is there a way to do this? take what i have, that isn't in an official profile, and just put it into a profile?

thanks.

Firefox Nightly cannot be found in the 'Software' store, so probably the only way to download it is by going to the website and getting a tar.bz2 file. I got that, extrated it and placed it in the/opt folder, made an application shortcut, added an icon, and now it's working like a normal app. The problem arises when it tries to auto-update. Firefox Nightly updates very frequently, sometimes more than once per day, and on windows, I used to get a notification saying that a new update is released, and if i wanted to install it. Clicking yes, Firefox would update and restart within moments, and restore all my tabs and windows seamlessly. Here on Linux, I have to manually download the new tar.bz2 file, extract it, replace it in the specified folder, and launch Firefox Nightly again, and again and again usually once per every alternate day, whenever the new update comes. Is there a solution for this? Will Firefox someday release a .deb file for easy installation and updates? My PC : Dell Optiplex 3070 OS : Zorin OS 16 Core (based on Ubuntu 20.04 LTS)

Hi

I recently downloaded Firefox from the main download page https://www.mozilla.org/en-US/firefox/ The actual download link was: https://cdn.stubdownloader.services.mozilla.com/builds/firefox-stub/en-US/win/aeb02dfeae750c7fa2abe9c7bc07b48193110ac61e2169456253638270735d21/Firefox%20Installer.exe

I normally check my downloads using https://virusscan.jotti.org or https://virustotal.com before I run them with admin privileges. Anyway when I uploaded to http://www.virustotal.com the first thing I noticed was that it had never seen the hash before! (SHA1 hash is 3a974b7394597de41230f7517c293e4b6386eeab.) Once it was uploaded, it was promptly detected by the Cylance antivirus engine.

Can somebody please get in touch with Cylance? I suppose I could contact them myself; however, I prefer not to report it as a "false positive" on the off-chance that particular download actually is corrupted or I got a man in the middle- after all, it's surprising that VirusTotal has never seen this hash before.

installed new Windows 10 update Now Firefox icon leads me to Bing "settings" option claims Firefox is default browser but it isnt
