Diễn đàn hỗ trợ Firefox

Whenever I try to download a rar file, like a game from itch.io,0 it automatically fails and doesn't download even after retrying multiple times.

Hello,

James here. I CAN NOT find the Firefox application file location. There is no option to show file path upon right click of the desktop icon and I can not locate it in File Explorer. I have done an entire (C:) drive search and turned up nothing. C:\Users\(username)\AppData\Local\Mozilla Firefox does not exist in my file system. I am at a loss here and it's driving me bonkers!

Over the years I have accumulated important links in my Firefox Bookmarks bar and passwords file and it would be a disaster if for some reason my hard drive got compromised and I could no longer access them. Is there any way to copy the data to another set-up, independent of my laptop, from where the data could be retrieved in a usable form for display on another laptop or PC? Thanks.

My computer is OS X Yosemite version 10.10.5.

I have updated with the newest Firefox web browser today. Now I can't open Firefox because my computer is too old for this new version. Because I have totally replaced my old one with this new, I cannot go back..

And actually, I don't know what is the right version for my computer. I think I found some very long list of old versions(https://ftp.mozilla.org/pub/firefox/releases/), I don't know which one is right for me and how to install from there - I tried some of them..

If anyone can post the link of right one for my computer and inform me how to install it from there, I'd really appreciate it..

Than you.

I use debian and firefox-esr.

I have problem right now!

I used firefox version 105.0.1 for short times, then firefox transformed my profile to new version profile, so now I can't back to 102-esr version again, I have this message:

`Your Firefox profile cannot be loaded. It may be missing or inaccessible.`

So i try this command to fix problem

firefox-esr -allow-downgrade

or

firefox-esr --allow-downgrade

But still can't downgrade, So I have to ask could I downgrade? else I have to wait for new esr version?

What's the next firefox-esr version? or release date?

My HP Omen has 2 hard drives. Originally, Firefox was installed on the C: drive and working perfectly. In order to clear up space, I tried to use the Windows Move feature to move the program from the C: drive to the secondary (and larger) E: drive. Since then, Firefox won't work aside from opening a Firefox window. It will load no pages, settings, etc.

I've tried uninstalling Firefox from both the C: and E: drives. Searched for any remaining files and deleted them. Deleted Old Firefox Data folders. I've reinstalled Firefox, without the option of where to install it, but it still fails to work at all. I get an error message regarding a missing file, VCRUNTIME140_1.dll. I've searched for the file and it's NOT missing. It is in both the Firefox folder and the Windows/Systems32 folder.

I've searched for data in the Users folders that might relate to Firefox but NOTHING seems to work that will allow Firefox to work again. I've tried putting Firefox in Troubleshooting Mode but it won't restart as it says it needs to. It just won't work!

If anyone can just tell me how to COMPLETELY remove Firefox from both hard drives so that I can just do a clean, new Firefox install, that would be preferable. I know how to import bookmarks from Chrome.

If anyone can offer some help for someone who isn't great with computers, I would greatly appreciate it. If you need any other information, please don't hesitate to ask.

Hi, I have spent hours this morning trying to diagnose a problem with Firefox Update 115. It is Unstable and I can't Stream Music from Youtube or even Amazon Music. Web pages from sites I use everyday are out of order when displaying text as well. It's a real mess. Now, here's the kicker, I haven't been able to stream my music from both aforementioned websites, but get this, if I use the Incognito Browser, Music streams No Problem. Seems like you guys broke something in the main FF browser. I have spent hours trying to debug this and have concluded that your most recent Update has broken streaming links. I can't rollback the Update and that is even more frustrating. Please Fix This. BTW, your Help Pages really stink. Sorry, but they offer no help when the problem is clearly FF. Kind Regards, Joe White

At some point every night, my Firefox (and only Firefox) reverts to version 111 from the latest version. This happens on 2 different Windows 11 machines.

I can only get Firefox to run again by running from command prompt with "-allow-downgrade" option and then updating again.

I usually don't notice until I launch Firefox the following morning and it gives me a message that the profile was created with an older version and to exit or create a new profile.

I've had Firefox open and then it reverts and it gives me a XULRunner error about the profile being used by an older version.

I don't have any special backup or restore software running and the physical files in my Firefox folder in c:\program files\mozilla firefox are being physically pushed to a prior version dated 3/21/2023.

On both machines, I've completely uninstalled and reinstalled and it's good for a day and then reverts.

No log entries for the reversion can be found. It's just back to a prior version.

I've never come across anything like this before and have scanned for any malware or other issue, but haven't found anything.

Firefox saves files that I only wanted to open with another application.

I checked the previous solutions in the forum, but they did not work for me. (Windows 11) I changed in system> general > download , applications > the app to open that file type and it works, but besides this Firefox keeps saving the files in the default download folder.

I tried also about:config browser.download.improvements_to_download_panel to false. browser.download.start_downloads_in_tmp_dir change to true No change - still saving copies.

Dear community,

As I use a few self-made unsigned add-ons, for several years now I have been using the Firefox unbranded builds on Linux with great joy. In the past these became available for download shortly after a regular Firefox was released. Lately though things have changed. The current latest release for unbranded is stalling at version 107. So it's getting further and further away from the official Firefox, which is at 109 at the time of writing.

Obviously I'm concerned my unbranded Firefox is not getting the same security updates any longer. I do realize there's alternatives for supporting unsigned add-ons. Running a Firefox nightly or developer-edition is something I'd want to avoid, so for me these aren't real alternatives. I've also tried tracking unbranded info on bugzilla.mozilla.org, but couldn't find anything relating to this 'lag'.

Where can I find more info on this topic? Are these unbranded builds being discontinuated?

Thanks for reading, keep well!

Normally I use side-berry to hold all of my tabs - the panel normally collapses and hides to the left of the screen - showing just the favicons of the website.

After the most recent firefox update 107.0 (20221110173214) there is now a large bar that i can't remove!

I have a CSS file for appearance, which i have included below.

any idea how to shrink this dead zone? I would really like to keep using my fun tabs.

I'm having a problem with Win 11 that will likely require that I reinstall the OS. I decided to move most of the data in my User folder by right clicking and changing the drive from "C:" to "E:" in the Locations tab. Firefox was closed as a I did this, it worked fine, and then I restarted the PC. Upon opening Firefox none of the extensions are working and I'm not sure what to do.

I have a problem with opening files: Mozilla keeps saving them and ignores temp folder. I tried to modify browser.download.improvements_to_download_panel in about:config, but nothing happened. Can anybody help me?

Trying to download nord vpn and is says "failed" tried to download a receipt for the purchase of above and it says "failed" the browser on Win 10 is set to save files to downloads

Hello

I got a new Asus Vivobook Core i9 16G Ram I did the basic Windows 11 installation for the Laptop and installed TotalAV.

After all Windows 11 updates passed, I wanted to install FireFox anf got this issue: Firefox cannot start correctly (0xc0000022) after version ..

I tried several time to close all Firefox task, uninstall, remove all files from existing profiles (local, roaming, etc...) so as all files under "Programs"". I made sure to get the latest code, but I always get back to this issue.

While opening FireFox, I immediatly get a Crashed Tab reported. Even the Settings are not opening in a Tab.

I even tried to use a older version. Same issue... Never the less I can Update the older version in "About FireFox".

After update I see 122 installed

I used FireFox for many years, and wanted to continue.. In the meantime I installed Opera

Any help is appreciated. Thank you in advance Laurent

I'm currently using a Windows 10 desktop computer most of the time, but will need to use a Windows 11 laptop for research travel several times over the next several months.

Will it be possible to copy my profile from Win 10 to the Win 11 computer, use the Win 11 computer for a few weeks, and then copy the profile back to the Win 10 computer?

Or is there something different about Firefox working with Win 10 or Win 11 that would keep this from working for me?

(BTW: Using Sync would probably not be feasible.)

Advice will be much appreciated!

HI! I've been trying to install Firefox on my new Acer Chromebook by following this article: https://support.mozilla.org/en-US/kb/run-firefox-chromeos. However, whenever i get to the last step, it says "no remote refs found similar to firefox". I have no idea what i'm doing at this point, any help?

I have Mac 10.12.6 on an "early 2009" 27" iMac. I'm waiting for the new 27/32inch iMac until I upgrade hardware and operating system. The release notes with FF V115 say in part " Users on those operating systems will be migrated to the ESR 115 version of Firefox."

I want to clarify that when I update to FF 116, FF will automatically install the ESR version, or will I need to do this manually? Also, will this update take a long time, like FF will be installing a totally new (ESR) version, rather than "just" the usual update?
