As per this issue I reported a while back, I was experiencing odd issue with automatic redirect to HTTPS for some private development sites.

I finally found a fix for the issue. The problem appears to be with DuckDuckGo Privacy Essentials Extension which apparently *may automatically redirect to the http site. In order to prevent this, I added my development sites to 'Unprotected Sites' and this prevented DuckDuckGo from doing the automatic redirect to https.

• - Odd thing is that I had multiple domains pointing to the same web instance and only one of the domains was having this issue with the DDG extension. Both were going to the same IP through a HTTP proxy. The proxy and web server were not the issue. This symptom points to an maybe an issue in Firefox....

In summary, be wary of odd redirects and the DuckDuckGo Privacy Essentials extension if you are doing web development work.

After the most recent update to the browser, I am no longer able to successfully login to many websites. Example for me include: Xcel Energy, Aol Mail, my local City Utility website and no doubt others I have yet to discover.

I know this is a browser dependent issue because Google Chrome is still able to access these sites just fine, but after the latest update to Firefox it no longer can.

It's able to load the login page and the site, but login in specifically returns either an error that shows on the webpage, or the URL displays some form of error code. Or in AOLs case it simply says "Uh oh. Looks like something went wrong. Please try again later." with a length authorization error code in the URL.

Any help with this would be appreciated. I've cleared Cookies, Cache, Active Logins and every other History Clearing option set to "Everything" as the length of time back to clean-up.

Like I said, this is a Firefox dependent issue due to Chrome accessing these sites just fine. I'd rather stick with Firefox over moving to Chrome but if no one can solve this problem then I guess it'll finally be time to ditch Firefox sadly, even though I've been using it since the early 2010s.

Even though I have removed the cookies for Facebook, the Manage Cookies screen shows a HUGE storage space. FF v99.0 on Mac

==

from preferences page: Your stored cookies, site data, and cache are currently using 17,179,869,184 GB of disk space.

almost all are Facebook storage. I'm feeling a little reluctant to delete all site data. If I clear all cookies and site data will that fix the issue? will the issue re-occur?

Hi! Since yesterday, in Outlook, my font size became very tiny for subjects and categories. I can barely see it. Can you please restore them to normal sizes?? I am desperate trying to read them. Thank you! Shirley Savva

As of last week, I am unable to reply in the reply sidebar in a Slack thread. When I click the reply icon associated with a comment, the sidebar opens and a loading icon is displayed for a second but then nothing happens; all I get is a white sidebar. I have updated to 99, shutdown and rebooted, opened Slack in an new window and nothing allows replys. I am running Windows 10 Pro, build 1903, 64 bit, i5 processor, 16 GB RAM. Suggestions?

I've noticed that some websites will endlessly spam the console (in developer tools) with rubbish, and I would like to be able to block that from happening. I'm ignorant about this sort of stuff in general, and it confuses me how a website can even access my browser's console to begin with.

The latest example I came across which caused me to finally ask about it, was some strange JavaScript spam with some kind of < div > (had to edit this with spaces to show it in the post) structure containing over a thousand characters. This entire thing gets spammed in the console at a rate of a few every second. I recorded a short gif of it, which imgur seems to have converted into a video: https://i.imgur.com/dosMZjo.mp4

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

I had the same problem like the link below when I use firefox.

https://www.reddit.com/r/firefox/comments/tjxh7s/videos_freeze_when_window_isnt_in_focus/

So, did what the instruction says and it solved the problem regarding discord.

But, since I changed that setting, firefox doesn't remember my google login or dark skin settings of other websites (it was always automatically logged in when I use YouTube. Not like it remembers the password).

How can I solve it? I resetted firefox multiple times.

I have at least one extension that has had a later version than what I have for days and firefox is not updating it even though everything is set to auto-update. i hate to have to uninstall/reinstall it since I will lose all the settings I have in place. Any ideas?

The developer says firefox is just waaay behind on extension updates and it isn't their fault.

I just ran "C Cleaner" to clean my computer. At the end, it said to ask the browser if there is a 64 bit Windows compatible version available? It takes 21 seconds to open my browser. That seems like a long time. The message went like this "\??\C:\ Program Files(x86)\MozillaFirefox\firefox.exe" How do I know what version of Firefox I am using?

This is a moan more than a question. About every six months or so my bookmark sidebar disappears because i have clicked Control and B without meaning to. And that is how to get it back again. Except, I never remember and search all over the page (View, Options etc) without finding how to get it back. So I eventually do a search for how to recover it and find all the archived guides from when other people had the same problem and the same question and ther same frustration. So my moan/quesion is this: why the blankety blank, doesn't Firefox add something into the menu (View or Options or somewhere) that says "Show toolbar permanently". Would save all this frsutration and irritation. The impression I get is that Mozilla thinks we should not want to have the menu on screen all the time. But that is the problem with users! We have our own way of doing things! Please!

OneDrive links recently stopped opening (browser tab shows the OneDrive icon but the page shows no content); Edge continues to open the links. I am running Firefox 99.0.1 (64 bit desktop).

When I restart my computer, I am logged out of all websites although I did not select settings such as "Delete cookies and site data when Firefox is closed". This only happens with reboots and not on Suspend.

I saw two similar posts but the options look like they changed name since then: https://support.mozilla.org/en-US/questions/1319622 https://support.mozilla.org/en-US/questions/1289909

I tried to apply the solutions linked there, to no avail.

This behaviour only happens on my Garuda Linux and not on Pop-os. Thus I am not sure here is the right place to ask this question.

Another strange bug which may be related is the following: if I zoom in a page (say set it at 120 percents) then go to another tab and then come back to the page I zoomed in, the zoom is reset to 100 percents.

Any help would be greatly appreciated!

Hello,

I noticed that a setting on the about:config page was removed: the "security.csp.enable" setting. I was using this setting to disable CSP to be able to load local JS scripts on some non-locally hosted sites, for debugging and development, work related purposes.

Was this setting really removed? Is there a way to disable CSP on Firefox on the latest version?

Thanks! Gabriel.

my computer broke about 2 months back and i am wondering if i can access the tabs from that device from another device since the original was synced (or i.e. is the a function in Firefox that lets me see all synced tabs from all connected devices)

going to the regular synced tab area there isn't anything from that computer there,

Firefox v.99.0

Hi,

My partner has an issue with Google working within Firefox (FF). The problem started around 27 April 2022.

In short:

• • Both gMail and Google Drive keep saying “Ooops … the system encountered a problem (#2003) - Retrying in x s…” and “Not Connected”.
  • The above message may stop for a period and then gMail within FF fails to render its pages properly. Icons go missing. For example the check boxes to the left of the emails disappear while the remainder of the subject lines remains. Menu icons across the top of an open gMail document disappear (like Download, Report Spam and Delete icons ….). This seems to suggest a cache issue.
  • Search within FF using Google fails also. After entering search terms and pressing ENTER, nothing happens.

Note:

• The stand-alone Google Chrome environment works fine. So gMail, Google Docs, Sheets etc work OK in the stand-alone Google Chrome app.
• Duck Duck Go search works within the FF browser.
• I have noted that if I simply log into MY Google Account under Firefox on her PC the same problem occurs.
• If we log into my PC the problem is not apparent using either of our Google Accounts. So it appears to be an issue on her PC.

I have tried :

• Flushing the cache in FF for all time, including data. Then rebooted.
• We have followed your procedures under “Help” ie Runs a Firefox a tune up; used “Diagnose issues” and “cleared the startup cache”.
• Have run Sophos AND MalwareBytes across the whole laptop. No PUPs or malware detected.

I uninstalled FF using Revo Uninstaller which initially uses the standard FF uninstall exe then it scans the drive for removes all FF files and entries within the Registry; then I re-installed the latest version of FF. Rebooted. No luck here either. I assume there is some remnant file that remains on the hard disk as some settings are retained after a new install.

Hardware: Lenovo ThinkPad , model 20QFS00B00. OS: Windows 10 Pro, vers 10.0.19044 Build 19044, 64 bit Firefox browser: is up-to-date; vers 99.0.1 (64 bit)

I can't find any recent issues related to this specific problem. Please advise what to try next.

Of course I'm happy to provide additional info if required or work through different scenarios to isolate the issue(s).

Thanks in advance for any assistance, Steve Gee
