Firefox Support Forum

today 4/18/2024 firefox update. Now browser is slow. Task manager showing currently 15 firefox open, even though only one new tab is selected. It is causing laptop to overheat, fan is running constantly. Nothing else is open.

I recently purchased a new Mac Book Pro. After migrating my data from my old one I noticed that when using Firefox my Facebook account was not working properly. I no longer could access my own page or the pages of friends. However, I could access some group accounts I'm associated with. On Safari, everything works fine. I suspect something must have been compromised during the data migration.

I deleted the Firefox app from my new computer and then reinstalled it but to no avail. When I'm in Facebook and try to access my page I get an error message. My OS system to up to date and apparently my Firefox is up to date as well. Any suggestions? Thanks!

I've been using the Firefox browser, and recently when downloading files with Firefox, sometimes it prompts: .part could not be saved, because the source file could not be read. # see image #1 I'm trying to download file to disk D. But the fail tips is download .part file to disk C. Maybe firefox is using some file cache policy which I don't know. I also checked both two location, my account have read/write access.

I can try to resume the download, and the download progress will increase, but about half a second later it will fail again. If the file is small and my internet speed is fast enough, after several attempts the file will eventually download successfully. # see image #2 I have tried using "private window" or enter "about:profiles" to create/use a new and clean profile, but the issue still persists. # see image #3 I tried using other download tools like "Internet Download Manager", and the download was successful. It's ok for use chrome to download the same file to same disk location. The problem recently emerged, it didn't exist before. At least a month ago, the same computer didn't have this issue. I'm not using parental controls.

https://tasmota.github.io/install/ This is an example of what i am tryingto achieve bit no matter on which site i am , i do not get to choose from ports and my devices and always faults out saying similar messages that the browser does not support web serial in one way or the other for any site doing similar task. error message is as shown in the image shared basically complains of browser not supporting web serial.

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

Help! I updated and now all my tabs are crashing and I'm on a deadline! I tried to rollback but couldn't find the exe. Here are the last 5 crashes:

Firefox is using very high memory and crashing a lot that causes my whole computer go hanged and I had to force shut down my computer resulting in lose of my work. I have 16GB of RAM, and Firefox was using 12GB and thats insane.

I can't open firefox. message says "firefox quit unexpectedly" and it won't reload. I tried Force Quit. I tried restarting my computer. I tried completely shutting computer down and restarting. It happened very suddenly yesterday.

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

I am receiving this error message when I try to log into my router. My router has a certificate from Let's Encrypt.

What settings do I have wrong?

Regards.

I have at least some computer knowledge but not enough to understand the link on the crash report that says what this report means. Is there a cliff notes version of why my firefox keeps crashing. I have link to the page so I am not sure what info is needed to help me. I can give screenshots or link info. I'm not sure if it's safe to post everything on report or what is necessary.

After signing into an account with Schwab.com, the site has a "Launch" button that opens the Schwab "Streetsmart Edge" trading platform. However, after signing into Schwab.com with the Firefox browser, clicking on the "Streetsmart Edge" Launch button does not work. "Streetsmart Edge" does not open.

This problem only occurs when using Firefox. If using Microsoft's browser there is no problem.

Previously, until about two month ago, the Firefox browser never caused this problem. It worked fine for many years.

I prefer the Firefox browser versus Microsoft. Please research and repair this issue.

I've got an M2 MacAir running the latest version of Sonoma. Within the last week, the battery power has fallen off a cliff. It barely runs for a couple of hours and recharging takes nearly half a day. I'm not running anything unusual just social media & YT videos. This seems to have coincided with the latest Firefox update. I was wondering if this might be contributing to it or if this is a common problem since Sonoma & FF updates?

Anyone any ideas?

I saw through several threads on how to try and fix this issue but none seem to work for me, when im trying to watch a video on regular firefox it doesnt work but on safe/troubleshooting mode. and it works when i put the video in a new tab but not on the main site. and while looking in the console i get this "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://static1.e621.net/data/ab/71/ab71a84c62b9d77fa0eb68c5e64dc165.webm. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 206. any help will definitely be nice

open app on desktop, closes within 40 seconds whether browsing, playing a bookmarked game or just watching opening page. I uninstalled app, reinstalled with saving bookmarks then without saving apps, it stills closes

I keep getting this message every time I try to access a website I haven't accessed for a while : see attached graphic.

How can I get this to stop ?
