Diễn đàn hỗ trợ Firefox

I am using Firefox Browser V81.0 (64-bit) on MacOS Catalina and I'm experiencing issues with downloading files specifically from Google Drive. I can download other files using Firefox, but it doesn't work when using GDrive. I know it's an issue with Firefox because I've tried downloading the GDrive files using Safari and it's fine.

What happens is I'll click download and then there is no prompt that asks me if I'd like to download the file.

I also looked at this thread and followed the troubleshooting measures (including clearing the browser cache and starting Firefox in Safe Mode), but it did not solve the problem: [https://support.mozilla.org/en-US/que.../1157677]

I've also tried un-installing/re-installing Firefox. And I have my adblocker disabled for Google Drive.

Any suggestions for how to resolve the problem?

Today I tried to update Firefox through the Help/About Firefox dialog. The update from 85 to 86 appeared to go fine. I got the Click to Restart Firefox and complete Update button, and the application restarted when I clicked the button. However, opening the Help/About Firefox dialog again displays the message "Firefox is being updated by another instance". It is not, so it appears that this update has not completed correctly, and, in this state, I suspect that further updates won't work either. Has anyone else seen this issue?

Yesterday I updated Big Sur (11.2.2). When I started up Firefox I got a message indicating that I had to update my version of Firefox. I clicked on the link and it sent me to Apple and Apple said it was only supporting IOS. I never could find a link to get the latest version for MACOSX as it seemed that the three places I tried were for IOS. What/where is the URL for MACOSX ? According to FIREFOX I am up to date (86.0) 64 bit

I am on a metered/limited phone hotspot connection most of the time. When Firefox indicates there is a new update available, I need to know how much data transfer it requires. If an update is large, I need to take my laptop to a free WiFi location. Thanks

I've ran apt remove --purge firefox and completely deleted the ~/.mozilla directory, reinstalled and still get a Mozilla Crash Reporter window.

If I try to run firefox from terminal I get: (Running in safe mode (firefox --safe-mode) makes no difference.)

   [GFX-]: glxtest: libpci missing.  

I haven't made any config or extension changes since it stopped working, and not sure what could be causing this. I don't mind starting from scratch, just need Firefox back. :)

Hello! I am using firefox on windows10 I am facing problems with my firefox browser, some buttons are not responding where as the same buttons in site work well and good in chromium based ones. This is my first problem

My second problem is that I uninstall firefox completely and install again. I am getting a welcome window saying "Firefox has been installed before. Let's get a new copy". Please help me get an experience as if i am installing firefox for the first ever time on my machine.

Please address them both

Would love to switch from Safari to Firefox on my iPhone. Found Mozilla Help instructions, but there is no listing in the App Store for "Firefox for iOS page." I see only Firefox Private Safe Browser and Firefox Focus: Privacy. Neither shows a Get or Install button. I tried tapping the first icon of these two. When I tap the icon, I see "open this link in external app? with a link. I can click ok or cancel. When I do either of those, it just takes me back to where I was. Please advise...

Hi, I want to move Firefox to a new PC. I know there are many guides on how to do that, but what I'm most concerned about are my open windows and Tabs. How do I preserve those on the move?

Thank you.

When I download a file with my custom extension, i.e. "sample.abc", it is becoming "sample.abc.txt"

This does not happen in Google Chrome. Any idea why this is coming over as "text/plain" mimetype and how to fix it?

What is causing the browser to revert back to previous version? The previous version was 85.02. I have uninstalled Firefox and reinstalled v86.0. Eventually, the browser reverts back to the previous version. When I tried to open the browser, the following message appears:

You've launched an older version of Firefox Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for the installation of Firefox.

                                                                               Exit              Create New Profile

I did NOT enroll in any FF studies. Yet, moderator Cor-el said the app.normandy preferences will install new features and 'shield studies' anyways. I stopped downloading FF updates after v.84. I wanted to avoid the disastrous change to the print function that showed up on another computer. I spent hours trying to figure out what happened and how to get rid of of it. Nevertheless, Firefox installed this unwanted print 'update.' So my question is whether it is safe to turn off or delete all the app.normandy preferences in about:config ? Or do I only need to change the settings on a few? If so, which ones. What happens if I change these?

Dear all Maybe, someone is able to help me out here:

We're supporting several companies with the following setup: User's are working with an office computer. However, they are also able to work from home via VPN and RDP. Folder redirection is enabled and directs to a network drive.

Since Firefox usually only updates while the application is running, we regularly face the issue where the Firefox profile wasn't able to load on the office PC because it was opened with a more actual version (the one from the Remote Desktop server) earlier.

Is there a way to update Firefox without launching the application first? Preferably from command line so it could become part of the logon script? All I found which looks helpful is the section "Service Command Line Parameters" in https://wiki.mozilla.org/Windows_Service_Silent_Update. However, I wasn't able to get it working so far.

Read support article about importing username and password info direct from .CSV file. I see at the bottom of that article that if no such option presents (Import from file), I am to ensure that signon.management.page.fileImport.enabled is set to true. I don't see that operator within the listing of configuration options. I can create that operator and set it to true, but that doesn't make the 'import from file' option appear in the three dot drop down menu within the Logins and Passwords page. Has the title or location of the fileImport operator changed, been moved?

Hello, is there a way to turn off the new print function. I want my print program to open and not a complicated print program that cannot be used by us. Since this new setting, we can no longer print properly and have to do all print jobs with a screen print.

I cannot suddenly download my bank statements I am getting this message within the bank website:

"We're sorry, there was an issue when trying to retrieve your documents." this has only happened recently there reply to the question is as follows: Thank you for your email.

We understand experiencing issues with the website can be frustrating. This error is normally received when there is a browser compatibility issue. If the current browser does not allow you to access the documents, we would suggest using one of our other supported browsers: Internet Explorer, Firefox, Safari or Chrome.

Also I am having problems getting into my messages an Error comes up around 3 times before I actually get into them.

Any help would be gratefully appreciated....thank you
