Firefox Support Forum

I use firefox on fedora 38 and after update firefox about a month ago . i got this error when use private mode ,for thai languge it just error but in normal mode it ok .

Issue description: Similar as https://support.mozilla.org/en-US/questions/1294366 But I'm not using USB wireless receiver, I'm using wired network adapter for connection

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.

Enivronment: OS: Windows 10 professional 22H2 Firefox version: "124.0.2 (64 位)", auto update is enabled, it should be the newest version. security software: windows defender

browsing website (reddit or amazon for example), the window scrolls to the top every time I move the mouse. doesn't happen all the time though, and only in Firefox. I've serached the internet and can't find anything related. Please help

This has been happening to me with recent updates of Firefox, and I am very close to dumping a browser that I have used for years because of it. I go to load pages and it just sits there and spins and spins. In the time I take to open another browser like Chrome and copy and paste the exact same links into Chrome, where the download of the web page is practically instant. I go back to Firefox and it is still spinning and it is just ridiculous. I have no clue what would be causing this. After it finally loads a page, it seems fine on subsequent loads of pages.

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

Using the arm64 version of Firefox on a Surface Pro X causes several graphical issues. These issues started either with a update of Firefox or drivers.

This topic has already been reported, please see here for more information and documentation: Reddit: https://www.reddit.com/r/firefox/comments/182iojx/firefox_arm64_graphical_problems_on_surface_pro_x/ Mozilla Connect: https://connect.mozilla.org/t5/discussions/firefox-arm64-graphical-problems-on-surface-pro-x/m-p/52086

What can be done to report this issue and help it getting fixed?

For some time now, e-mails have been arriving with a delay, e.g. from April 15, they arrived only on April 18. The mail is on the home.pl server pinned via IMAP.

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!

Hello Good People,

I noticed that the snap version of Firefox had a lag issue when typing into input field. For example, when composing an email and wanting to use backspace to quickly delete a misspelled word, then backspace works slowly, stuttering and jittering. If I hold down a key in the input field it also lays the character down in a stuttery, slow way.

I tried reinstalling the system and that solved the issue. But it has returned again. Maybe it was an update. I also installed WINE and waybridge to get some windows plugins to work on my DAW. I don't know if that has affected it.

I also tried removing the snap version and installing firefox using the terminal but the problem persisted.

It's an annoying problem. Any advice appreciated.

Just recently Firefox seems to have its downloads capped at 15-16 meg speedtests show the full 1Gig speed OPERA AND EDGE both download at the full 999 megs but firefox has recently stopped downloading any faster then 19 meg

what in firefox could be causing this its not happening in any other browser.

Ever since the update, I have had pink flickers on videos on youtube and twitter. They last for less then a second, so I couldn't grab a screenshot of it. After doing some reading online, I turned off hardware acceleration which turned the pink flicker black and now effects several sections of the web browser.

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.

In the Firefox settings, it says "Account disconnected" so I click the sign in button, it opens the Mozilla website, and I successfully sign into my account online. Yet the browser still says disconnected. I've tried a few times. How do I fix this?

I just got a chromebook! Details:

Device name: Lenovo Flex 3 12.2" chromebook, 8GB ram. Intel N100 Device code name: IP Flex 3 CB 12 (pujjo, version 123.15786.0) Firefox version: 124.0.2 (flatpak) OS version: Version 123.0.6312.112 (Official Build) (64-bit) Chrome: Version 123.0.6312.112 (Official Build) (64-bit)

When I watch a youtube video with chrome my cpu usage is 20-30% When I do the same with firefox my cpu usage is 50%

Running `about:support` and going into `webrender_compositor` I get the following errors under `env`: 1. Blocklisted by gfxInfo 2. Blocklisted; failure code 3. FEATURE_FAILURE_WEBRENDER_COMPOSITOR_DISABLED

I have set almost all these force renders = True and even granted gpu access to firefox flathub but still no difference in performance. I am asking now because I am just going in circles in the rabbit hole.

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.

Mac OS 14.4.1

Firefox crashed and now will not open without crashing. I have trashed it and re-installed but still getting this error and cannot use the application. It will not open in Trouble Shoot mode. I even removed all files in the Library/Application Support

This is the problem report it shows:

when I search for a page after opening a tab. The page will load slowly then stop. I'll then have to hit enter again for the page the load. This does not happen with Chrome or Edge. Any ideas how to fix this frustrating issue. Thanks.
