Diễn đàn hỗ trợ Firefox

Has anyone reported this before? I am working as a contractor for a BigTech company. I am using an online platform/tool of theirs for several years now but after a recent update the work area doesn't show scroll bars anymore. That means I cannot scroll the editor window and can't go beyond the first page. This makes working (and earning money) almost impossible. As even for the tiniest edit I have to download huge tasks which is extremely time-consuming. An inquiry with my manager there indicated that other contractors on firefox experience the same issue. so they consider it a firefox compatibility issue of some kind. They gave me the advice to use Chrome, Edge or Safri instead. Well, I use firefox because I do not want to use Chrome/Edge... Don't know about Safari but my PC is on Windows... Any idea what can cause it and how to resolve the issue?

Ok, I screwed up.

I was trying to solve a problem I've been having with regular releases of Firefox and it occurred to me try the ESR release so I downloaded and installed it. The good news is that it solved my problem, the bad news is that I just barrelled into it without thinking, assuming that my logins and bookmarks would just transfer over like with regular releases. They did not. It turns out I should have made a backup of those things first and I can't open the old regular release of Firefox to properly back-up those things now. Oops.

I've been reading lots of forum posts here and elsewhere trying to get those files into ESR and I haven't been successful. From the profile manager I've located the profile that still contains that info and I've tried:

Copying and pasting the "logins.json" and "key4.db" files from the "default-release" profile into the ESR profile which didn't work.

From "about:profiles" I also tried to "launch profile in a new browser" of the default-release profile so I can open that profile and properly back-up bookmarks and logins but I get a prompt to create a new profile which I tried several times and only resulted in several profiles of the ESR release.

Then it occurred to me that If I could just delete all instances of ESR and open the old default-profile then I could back-up the logins and bookmarks, THEN download and install ESR again and import those files but before diving into that I need to make sure that won't loose my original default-release profile info.

So experts, does that sound reasonable? Delete all instances of ESR so I can open the regular Firefox? What's the best way of going about that?

Thank you.

I'm using a Windows/Linux client called WSL (Windows Subsystem for Linux). I've installed Debian as my WSL OS and for a long time I had Debian version 10. Firefox worked fine with ver 10 but this morning I upgraded to Debian version 13 (which required me to upgrade to the latest version of Firefox).

Firefox still launches okay but I wanted to change my home page to Google. So I clicked the 3 lines at the top RHS which showed me a popup menu but none of the options was selectable. Eventually I twigged that to change settings I needed to launch Firefox using sudo.

I managed to change the home page okay but I then realised that if I launch Firefox without using sudo, my new home page is ignored. Conversely (if I launch using sudo again) Firefox launches at a tiny size and can't be re-sized (at least, not using my mouse cursor). I've attached a small screenshot.

All I can do is to display it full screen and then I can tell that the home page is indeed now Google. I don't remember having these problems previously so can anyone give me a clue as to what I'm doing wrong??

Check https://piunikaweb.com/2026/08/14/firefox-x-images-videos-not-loading/ for details, but basically xTwitter/Melon messed again with their latest update.

Any word from those in the know yet? Having to use different browsers to see multi-pic posts is really annoying.

I have a windows 7 operating system running Firefox v115.40.0esr and the program runs but I am continually getting the error: The procedure entry point GetSystemTimePreciseAsFileTime could not be located in the dynamic link library KERNEL32.dll Is there a fix for this?

I encountered an issue where pasting multiple images causes the upload to fail. It seems like it cannot handle more than 2 pictures at once. Could you please help me fix this?

Hi,

I'm experiencing an issue with Firefox caching a JSON file.

My website uses a JSON file to display dynamic values. After updating the JSON file on the server, Chrome, Edge, and other browsers immediately show the latest data, but Firefox continues to display the old values even after refreshing the page.

I have tried: - Hard refresh (Ctrl + Shift + R) - Clearing Firefox cache - Private Browsing mode - Confirmed the JSON file is updated on the server - Verified that Chrome and Edge display the latest values

The JSON file is requested using JavaScript from my website: Main issue on this page: https://bloxvalues.net/blox-fruits-value-calculator/ and other individul item pages too.

Could Firefox be aggressively caching the JSON file, or is there a cache-related setting or HTTP header I should check? Any suggestions would be appreciated.

Thank you. Qaamar

Both Mozilla products spontaneusly disappeared from my computer. Firefox requested a reinstall, and all was recovered. Firefox completely disappeared, and I had to restore from backups. I am seriously worried. What is going on?

I was reinstalling my windows and created a backup from my old firefox into my usb drive. My backup failed and coudn't be restored, I'm confident that I use the correct password, tried to copy the file from usb drive into my laptop and select it from there but the result is the same, if you guys would be so kind as to guide me on how to restore my backup, since my password and everything is in there. I didn't create another backup since I believe that this one would succeed. Thank you in advance.e

When I sign in to Firefox it puts a message up saying Microsoft is no longer supporting Windows 10 and telling me to backup my info to get ready for Windows 11. I'm not planning to get Windows 11 as my PC won't support it. Should I ignore this message?

火狐浏览器更新后会自动清除C盘用户下的所有文件，安全软件阻止都阻止不了，下面是记录，已经被清除2次了，对火狐已经不爱了。

I am not concerned with anyone in my household gaining access to my passwords. If I somehow give a scammer remote access to my computer, does creating a primary password prevent that person from seeing any user names or passwords that I may have accidentally stored on my computer? I am concerned with third party scammers, not anyone physically gaining access to my laptop.
