Firefox Support Forum

Firefox works great on every other video site. But Youtube will not show or play video. I have refreshed Firefox, disabled add on. Restarted my computer, tested all hardware. No Bueno...

Hi Firefox Support Community,

I've been exploring the reviews on SGEats and noticed some performance issues while browsing the site using Firefox. The site has numerous high-quality images and interactive elements which seem to cause slower load times and occasional lag.

Are there any specific Firefox settings or extensions that could help improve the performance for such media-heavy websites? Would enabling or adjusting hardware acceleration settings make a significant difference in this case? Are there known issues with Firefox handling similar content-rich websites, and if so, are there any recommended troubleshooting steps? I appreciate any insights or recommendations to enhance my browsing experience on SG Eats and similar sites.

Thanks!

When I open a new tab, I can't automatically start searching anymore.

Here's a video: https://www.loom.com/share/ebcc8685187a4e2284cf40b75f7e134e?sid=9b0a3db3-fcac-4bae-9ff9-cdbe2b8b955b

Now, I have to click into the search bar to type. That's annoying.

Anyone know how to fix this?

I try to sign-in to my KP.org account and I get a white page with the message (Firefox has detected that the server is redirecting the request for this address in a way that will never complete. This problem can sometimes be caused by disabling or refusing to accept cookies.) I called KP and they said there was nothing wrong with their site. I added the URL to the cookies exception list with no result. I tried to paste the exact URL of the sign-in page into my bit-warden and it said it exceeded the 1000 character limit. I can sign-in on Chrome, but I prefer to use Firefox. any ideas?

Help please.

I had to factory reset my laptop (or rather, an IT support person took over my machine and reset it before I could back up things properly!). I was not able to restore my previously opened tabs (there were a lot, like >100). It appears that all of those tabs still are showing on my mobile version of firefox as 'synced tabs'. Is there a way to pull that sync information from my phone to my laptop? If I press on "synchronise tabs" will the phone receive my laptops current tabs (not what i want), or will it update the laptop (what i do want)?

Thank you.

Ever since Firefox browser updated, my Home (specifically Shortcuts) has been glitching.

They do not show up, no matter how many rows I add or subtract. Web search and Recent activity still works (to an extent) but Shortcuts? Never again. Please fix it ASAP.

I always keep two Youtube tabs open at all times on my computer. After a while of running, however, the site starts to get increasingly laggy, in a way that simply reloading the tab does not fix. (I am aware that this is likely a result of one of the extensions I have installed that affects Youtube's behavior, specifically SponsorBlock and Return Youtube Dislike, but I am not willing to uninstall these.) I also know of a "force reload" - pressing ctrl + shift + R instead of just ctrl + R in order to clear the cache or something.

However, whenever Youtube starts getting really slow, I instead like to do something I call "crashing the tab" - I open my system monitor, look for the current most CPU-intensive "Isolated Web Co" process, and end it. This pops up an error message in Firefox that says "Gah - your tab just crashed!" and offering me the option to restore it. After restoring it from this window, the performance is back to normal.

My question is, is this beneficial, or is it functionally identical to a normal force-reload? Is the improvement I see between this method and force-reloading the page just placebo? And if not, is there a simpler way to do it without opening a second program?

When switching from one tab to another, streaming stops and video won't play in background. I've tried all the main fixes suggested I've found. Nothing worked. Please help! Will be using alternate browser until fixed as it's too unwieldy for me to use this way.

Receiving this error: Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window.

My desktop app redirects user to a login screen on Firefox, and I want to automate it using Selenium. My current workflow: 1. Launch Selenium-controlled Firefox browser using GeckoDriver 2. Click on "Login" button on my desktop app. The desktop app launches the login screen on user's OS default browser using the default user profile (in which case I set in profiles.ini to the temp profile copy created by Selenium). 3. (ERROR) Popup on the above error is displayed

Code: import configparser import os

web_driver = selenium_webdriver.Firefox(executable_path='C:\\Users\\mnxl\\.wdm\\drivers\\geckodriver\\win64\\v0.34.0\\geckodriver') profile = web_driver.capabilities['moz:profile']

1. Path to the Firefox profiles folder

profiles_path = os.path.expanduser(r'~\AppData\Roaming\Mozilla\Firefox')

1. Path to the profiles.ini file

profiles_ini_path = os.path.join(profiles_path, 'profiles.ini')

1. Read the profiles.ini file

config = configparser.ConfigParser() config.read(profiles_ini_path)

1. Find the section for the profile to set as default

for section in config.sections():

   if config.has_option(section, 'Path') and config.get(section, 'Path') == profile:
       # Set this profile as the default
       config.set(section, 'Default', '1')
   else:
       # Set all other profiles as not default
       config.set(section, 'Default', '0')

1. Write the changes back to the profiles.ini file

with open(profiles_ini_path, 'w') as configfile:

   config.write(configfile)

I choose a new theme. After a while, I close Firefox. When I start Firefox again, my chosen theme appears briefly, then the default theme replaces it. Why? FYI: it doesn't happen with just one theme.

I experienced problems with Firefox on different Windows 10 clients. The problems are only with Firefox, other browser like Chrome or Edge have no issues. The occasional issues are that Firefox loads the websites either very slow (~ 30 to 60 seconds) or sometimes not at all. At the same time, other browsers like Chrome or Edge load the same websites fast and reliably.

All affected clients have a fully patched Windows 10 with the latest build, up-to-date Firefox versions, recent processors and plenty of RAM and I periodically clean cookies/website-data/cache/history.

What could be the problem and the solution?

I was unable to sign in Qobuz from yesterday. I have been using Firefox ver 115 to play streaming music from Qobuz on my Windows 8.1 PC as its sound quality is better than other browsers. Yesterday, I found nothing happened after clicked the SIGN IN button on Qobuz's login page, however I had no problem using Google Chorme to login.

So I uninstalled/re-installed Firefox, and tried different older/newer versions, still didn't work.

I tried another PC running Windows 10, with Firefox ver 124.0.2, got the problem.

Please fix the problem ASAP, Firefox team. Thanks.

Its purer sound is the main reason I use firefox, instead of other browsers.

Currently, when I try and open downloaded .txt files and .log files (that is, when I click on them directly from the download pop-up that appears at the top-right of the browser), Firefox inexplicably opens Aegisub on my machine as the app to use. This is in contrast to when I open it directly from within my file browser, where it opens the Kate text editor, as suggested by the default app option in the permissions of the filetype.

How do I change the apps Firefox uses to open downloaded files? I've tried going into my settings and looking at applications, but .txt and .log don't appear, so I'm not quite sure what to do.

I'm on Kubuntu 22.04.3 LTS, using the Firefox deb package.

hello firefox support, i recently signed into firefox on desktop but now i cant seem to remeber the account password so after making a new password after clicking on forgot password ,will i lose my bookmarks and ad-ons and all the customized settings? pls help me in this situation i dont want to lose my data pls .

I'm using FF on a Mac Mini, Sonoma, and for the last few days FF doesn't open in the same position it was in when I closed it. When I open FF it's about half of the size it was when I closed it. I then drag a corner to the size FF I want, but this is a very new issue.

There's also no way to add an exception? Just completely broken at the moment. I have to disable OCSP stapling to get it to work at all, which is less then ideal.

Currently using 125.0.3 (64-bit). I checked for newer versions of firefox and it's not saying anything. Chrome and Edge work fine. Encountered this on an android tablet with firefox, and went to desktop and hit the same thing.
