Diễn đàn hỗ trợ Firefox

Regarding the current state of Firefox and WebUSB, I have four thoughts:

1. Yes, Mozilla's concerns regarding the security risks are valid, but not insurmountable.
2. In my experience, this is the single W3C noncompliance that impedes my use of Firefox.
3. In my experience, an increasing number of companies/organizations are leveraging WebUSB, from core-functionality of end-user hardware to enterprise-level troubleshooting, configuration, and support.
4. If Mozilla permits the use of unsigned plugins for its Firefox Developer Edition because of the reasonable expectation that its users understand the risks, it stands to reason that the same could be said for WebUSB.

(There's no need to reply, really - this is only being publicly posted because there doesn't seem to be a way to do otherwise - I just wanted to go through the exercise of casting this message-in-a-bottle into the sea.)

Recently, I have not been able to upload a video to YouTube. When I try to upload it, the upload is stuck on 0%. I tried another browser, and it worked fine. This has not been a problem until. I have uploaded many videos. The last time was about a month ago. So, maybe there is some problem with an update. Does anyone else have this problem or know the solution?

I get the server not found error on almost anything.

Hmm. We’re having trouble finding that site. We can’t connect to the server at [literally almost any site] If you entered the right address, you can:

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

The site usually loads after I wait like 2-3 mins before reloading the site, or I force reload it around 7 times, but I cannot find a way to make the issue go away. I have refreshed Firefox, I have uninstalled and reinstalled it fresh, I have opened Firefox in Troubleshooting mode and the issue persists. I am at the end of my wits. Someone please give me something else to try.

Hello, I'm having an issue with how Firefox is displaying images on some of our product pages. The image appears to be zoomed in which cuts off the side of the product image. The exact same product page displays completely fine when using Safari and Chrome. I cannot figure out the issue. Please see attached images.

I have tried:

modifying the about:config page prefs:

   browser.enable_automatic_image_resizing
   browser.enable_click_image_resizing 

I have also tried resetting the zoom features (Command/Conrl +/-/0).

I have also tried reinstalling firefox and running the browser without any extensions.

None of these worked. Any suggestions?

So i use garuda linux(not sure if necessary but still telling). The ".mozilla" folder is about 134 GB! I have browsed it a bit and found a lot of this folders "vuzpdtyn.default-release-backup-crashrecovery", "tor50voj.default-backup-crashrecovery-", "profile-somestuff-backup-crashrecovery" Is it safe to delete the old ones from this?

So, today i opened up my firefox and loaded up youtube; it didn't load. I tried to check my wifi speed on speedtest by ookla...the website didnt work. Then i went to reddit to see if this was a bug affecting everyone anddd that also did not work. So, basically half of the websites that i use do not work right now and i can't figure out why. Everything was fine till yestderday and i havent changed any settings. Also, Wifi speed is not the problem here as i opened up ms edge and everything works.

Please help! Here's a reference image of how websites look ( imgur ) Funnily enough, imgur also did not work of mozilla.

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.

Yesterday I have updated tp macOS 15. Sine then I have trupuble displaying any webpages in Firefox 130. Th econnection just times out. Any other browser such as Brave, Safari, Home, Edge are still working as before teh update. How to fix this please?

Hello, when i fullscreen video on youtube video stops buffering. When i end fullscreen buffering immediatly starts and everything is okay. Back and forth. I tried: reinstall to lastest mozilla release, disable addons, stoubleshoot mode, increase cache in about:config and other public solutions i can google. When i look on "Statistic for experts" on youtube there are three bars and it shows: Normal size player: Connection Speed - some amount of kbps (works) Network Activity - some amount of KB (works) Buffer Health - some amout of s (works) Fullscreen: Connection Speed - some amount of kbps (works) Network Activity - 0 KB (doesn´t work) Buffer Health - 0 s (doesn´t work)

I cannot use Firefox or Thunderbird I keep getting an error code: PR_CONNECT_RESET_ERROR The problem started straight after the latest update a few days ago.

I have cleared the cache and cookies I turned off the addons and extensions I shut down the internet security I changed the proxy settings to "no proxy" I even changed cert9 to ccert9 and had firefox generate a new cert9

Nothing has worked.

HELP!

Just a few days ago, screenshot technique failed. I often copy an image from webpage. Right click technique. I am still able to do this. I have option of copy or Download. Download works but Copy does not. When I try to paste the copy into my Word document, I get a blank image (a square that indicates there was an image but the actual image is not there). How can I get the paste mechanism working again?

There's one specific field I fill in very often and for some reason Firefox is really keen on suggesting me two searches that I looked up more than a couple months ago, on a totally different site. I can't even remove these suggestions or add new ones. When I used Vivaldi, it'd learn what I insert (even if it'd end up suggesting tens and tens of options), while Firefox doesn't learn at all.

For sake of an example, let's say that the word I use every day in this field is XYZ. Not even once was it suggested to me, I've only ever gotten the two in the screenshot below instead. And I can't remove them using the Delete key as some other article suggested.

Speaking of which, I just noticed the same thing happen to the subject line in this form 🙃

Hello dear community! My firefox keeps crashing when trying to open a tab or close a tab. I can't replicate it since it happens on random tab-closing and tab-opening. I think it's just crashing when doing something like clicking anywhere and NOT when doing nothing while the system is idling. Thank you for your help! Here's a link of the crash report: https://crash-stats.mozilla.org/report/index/8ba8940e-954c-4e92-9153-0313d0241001

My Firefox now only opens to a partial page size, not full, even though I click to a full page and then close out.

Opening again just goes to a reduced size page.

I have backed up my profile, uninstalled Firefox and reinstalled and brought my profile back in.

Still the same problem.

I think there is a file that controls this that is corrupted.

Need help.

I have reinstalled Firefox on my Mac many times, completely removed all files using app cleaner, and reset Firefox by holding shift and option on start. Despite this, the app is very slow to launch, and when it does no pages load or render. Opening a new tab freezes the entire app for 15-30 seconds, and when the tab opens it is completely blank. Attempting to browse to a URL does nothing, and the address bar just returns to being empty. Attempting to open settings does nothing, although parts of the app that open separate windows such as the about version info and bookmarks work fine. The only thing I haven't done at this point is completely reinstalling macOS, so maybe there is something wrong with my system config. I first noticed this issue when using the early macOS Sequoia betas, and assumed the app wasn't updated to support it yet. However after updating macOS and completely removing and reinstalling all traces of Firefox, it still doesn't work. I am currently using macOS 15.1 beta, however the issue also persisted on 15.0.

I use Internet Bill Pay through my bank, and it has always worked correctly with Firefox. I have enhanced tracking protection turned off for the site secureinternetbank.com and I have cookies authorized in my exceptions list. Today I got this message:

Why can't I access Bill Pay?

Bank says it hasn't changed anything, and no tweaks I tried on privacy settings fixed it. I believe it's an issue with the new version. Can you tell me how to fix it or let me know when Firefox will fix it? The site works fine in Microsoft Edge, but I'd like to avoid using Edge.

Thanks.

As the subject says Firefox very suddenly started giving me terrible loading times, despite all the sites working perfectly fine on other devices and browsers. Issue continued with troubleshooting mode, not sure where to go from here. I will open youtube, it won't load about 5 thumbnails, I click on a video and it sets it to 140p and then it still lags the entire video as if I was using 1kbps internet. I tested my wifi connection and its having no problems. Something similar happened when I used to use Opera GX, it was fine for a long time and then one day terrible performance. Please let me know where to go from here. Windows 11 Pro.
