Diễn đàn hỗ trợ Firefox

I get PR_END_OF_FILE_ERROR when trying to load certain websites. I don't use any proxy or VPN, I tried disabling DoH. Also sometimes i get 403 forbidden cloudflare.

We deploy Firefox via a software called Pulseway and last night it reinstalled Firefox over the current installation for one of our users. When he logged in this morning, all his data was missing from the browser as it appears to be a fresh installation. I'm unable to find his previous profile in the AppData folders (checked by going to about:profiles and opened each profile). There is no backup for this info, and he did not have a Sync account set up. Is there anywhere else I could possible recover this data for the user? Thanks in advance.

I have encountered an issue very similar to the one described here: https://support.mozilla.org/mk/questions/1407928

Firefox (version 130.0.1 (64-bit)) is not playing audio through headphones. Have tried a number of sites - e.g. YouTube, internet radio stations, news sites.

However, unlike in the above-mentioned support article, the Windows App Volume and Device Preferences settings are set to default.

I have since also tried restarting my PC (Windows 10 ; Version 22H2 (OS Build 19045.4651) and resetting the App Volume and Device Preferences to the Microsoft default settings (see Image attached).

I also tested and audio plays fine through Chrome browser, VLC media player, Teams and Edge.

Would love to find a solution! Thanks D

This feature has suddenly appeared and I absolutely detest it! I don't need it, don't like it, don't want it! I have searched everywhere on how to disable it. PLEASE tell me there is an option to do that.

I have latest version of Firefox for Windows 10 and about 2 weeks ago the Last Pass extension from your website stopped loading correctly. The extension installs in the toolbar, but does not work. It partially loads and then freezes up. I was able to resolve by removing extension and then going to Last Pass's website and downloading their Last Pass 4.0. Your extension is messed up. Tom Weaver

I have 6 websites that I currently cannot sign into using Firefox. Support tells me to use those two crap browsers Chrome and Edge. I end up using Edge because it is embedded in my computer and I cannot delete. I will not install Chrome and have put on Avast Secure Browser and CClean browser. Both are just Chrome with a new gooey. My Father is also having the same trouble. Most of the sites are for Utilities and rewards programs. Avast is also blocked. Are you aware and working on getting this fixed?

I am on endeavourOS (linux). Whenever I try to upload images for a profile picture to sites like youtube or X, the image becomes corrupted and doesn't upload correctly. It did this with whatsapp too and I had to use a separate app for it. Other posts said that disabling "privacy.resistFingerprinting" would fix it, but it's already disabled.

Attached below are an example of this bug and the contents of this image when viewed on a text editor.

When i do update my configuration settings changing by itself. Example, "browser.cache.disk.enable" is "false" but after every updates its always changing to "true". This happens only after updates.

I just noticed that when I start writing in the Firefox URL bar there is a blinking straight bar that remains at the start. And if I click of somewhere else and then start writing again, the bar remains blinking at the start of the new text. I also don't have the straight line you get when moving left or right in the text using the arrow keys.

I couldn't capture the bar with a screen shot so I have edited the images to where the bar is when beginning typing, and then after I have clicked of the text bar and then entered it again and typed some more.

Thanks for any help I can get.

I have a IP intercom that only works with Firefox 127.0.2 Now Firefox automatically upgrades to the latest version and I'm unable to prevent this. I'm unable to manage my intercom with the latest version. How do I turn off automatic updates.

On certain websites I am getting scrambled text, mostly in headings and titles, not so much in body text. I have followed several tips from other posts like mine, i.e., installed Open Sans font, but that did not do it. I turned off hardware acceleration, and cleared the cache. The only thing that did work was to start Firefox in troubleshooting mode. I only have two add-ons running, Short URL and Dashlane, I doubt they're responsible for this. Any other ideas?

So, for awhile now when I go to some sites, the screen suddenly starts flashing, then it jitters and turns some light color (like a light green; not blue screen, not black). If I guess where the "X" is to shut down the tab that has the video, I can end this. Often, like on youtube, I find the problem is some ad video that was playing. The rest of the site is ok. But not always.

One site I wrote down a few days where it happened: https://www.nbcsports.com/philadelphia/eagles/eagles-face-giants-2022-playoff-opener?cid=sm_npd_rsn_phi_fb_mn&fbclid=IwAR3rGUEa0W8fElrzCWANSIUpti9VKlbn0iHyvcFsviajYExo5tcRSyWBJXA

scroll down to video and everything blinks, becomes unuseable

It happens in lots of places, though. It is not per se a YouTube problem or just a problem at NBCSports. I shell out to MS Edge, and it seems to handle everything fine, so I'm assuming at this point it is a browser issue.

One last point: after this happen the screen display is degraded even after I manage to shut down the offending tab or video. It takes a Log off/log back in or reboot to fix everything. The degradation takes the form of making the screen look a bit like a pointilist painting, although that's an exaggeration.

FF 109.0.1 64 bit Windows 11 NVidia GeFORCE RTX 3060 running studio driver 526.98 (I have switched periodically from / to their gaming driver, which doesn't seem to matter)

Any help, appreciated.

Is there any way I can completely disable horizontal scrolling? I'm using a laptop with a trackpoint (lenovo x230, Windows 10) and it's not terribly accurate, which means scrolling whilst a youtube video is going often makes it track backwards or forwards, and another website I use uses a horizontal click to send me to the next page, which sucks. I would prefer to just be able to disable it entirely. Thanks!

I swear to god I used to have it disabled, just need to work out how again.

When I open up the Add-ons Manager it shows Window Titler is turned on. But Ctrl-Alt-T no longer works, there is no button showing for it, and it seems to be gone. A button for it does not appear in Customize Toolbar. It is the single most important reason I stay with Firefox. How do I get it to work again? Thoughts appreciated.

How do I change the google account that Firefox visits first? Context: I have my work email set up for sync, but whenever I go to any google specific site or tool (Calendar, gmail, docs, etc.) it defaults to my personal account instead of my work account.

I am trying to add a password to the password manager for a specific URL like https://example.com/page. However after I save the password it save it to the address https://example.com and removes /page. Is there a way to change this?

Hi team,

I am a researcher and trying to collect data from crash-stats.mozilla.org for my research. However, I got 403 Forbidden for several days. Can you help me to resolve this? Thank you in advance.
