Hi, I check my storage for large folders and I came across folder inside Firefox profile called "cert-revocations" and its size is more than 400MB, can I delete it safely? What cons of deleting this folder? and why Firefox doesn't clean this folder periodically?

Hi,

I have a problem, which only seems to apply to Firefox. I am a developer for a site which uses LetsEncrypt certificate. When I access it via Firefox (and only Firefox), I get the error message as mentioned in the subject.

I tried to understand why this occurs. A quick Google just leads me to an issue with the Microsoft domain, and what I can understand was a Firefox bug.

Trying to figure out if it is a problem with Firefox, or a problem with the certificate. Any thoughts?

Is there an easy way to downgrade back from the beta channel to stable? The downgrade protection feature seems to be a major blocker of just installing the latest stable version. Noticing high RAM usage on Firefox 100 and crashes which is making it hard to use for a daily web browser.

A customer shared his Firefox login with me to share his passwords. I logged in with his account, downloaded his passwords and logged out directly afterwards, but now he is reporting that he has ALL my passwords. How can undo this? I never gave him access to my account and I never clicked on sync or something?

please take off the red add, the pop up total add sign that keeps popping up asking to paid for the add block I am 82 and on a fixed budget. I do not want this service. How do I get it off my computer. When I want to print an article from an e mail.I always have to remove it to save an e mail, or when I want to print an article, I read it later, and I see the total ad block on my printed article stuck on the printed page blocking out what I printed. Its very annoying to have to take it off the screen before I print anything. Please help me. George at [removed email from public]

I have seen this in some past versions of FF It usually goes away after a few upgrades

Instead of whatever it's supposed to display, you can see that it shows some random characters.

Annoying. I dont even remember what it's actually supposed to show

I have had it with Firefox playing cop. I really have. I have a site that I visit frequently but these past two updates have now broken my ability to sign into the site at all, even in private mode. All I get is the shield and human icons with the strike-through and the error message on the user name/password field that says: This Connection Is Not Secure. Logins Entered Here Could Be Compromised. Learn More.

I've hit the escape button, tried private windows, done everything I can including resetting which was my last resort and which I hate doing, there's no more whitelist, no way to bypass anything, this is totally unacceptable that I cannot get past this. Firefox is becoming more useless to me as they try to become more and more in control of what I can and cannot do. If there is no override to this, then I have to find a different browser because it's pretty useless to use one browser for some sites and another for other sites, don't you think? So if someone has a workaround for this problem, can you please tell me what it is?

Background: I am on the Beta track, currently running 98.0b4 on Mac OSX 11.6.1, until kinks are worked out of Monterey.

Issue: One of the latest FF upgrades has killed my ability to login to Netflix. I get an orange popup field stating "Incorrect password. Please try again or you can reset your password." The password is fine, as I'm able to login using my backup browsers, Safari and Vivaldi. The issue persists when I try to log in using a private window that doesn't allow any add-ons, so I don't see that as the issue.

Firefox is still my preferred and default browser, so I'd like to see this resolved before.

I have already selected firefox developer edition as the default browser from the Eclipse Enterprise Edition. However, when the browser is open, it cannot open the url generated from eclipse. Suppose, I hit the command 'run as server' on a jsp file. If developer edition is already open, the file does not get open on a new tab. However, if the browser is closed, then it opens with the jsp file.

I have tested that with google chrome and firefox normal edition and in there, it works absolutely fine. But I don't know what went wrong in the developer edition.

I have uploaded two pictures for the convenience.

Recently i found that the memory usage can be very large when watching live-stream,tried many ways to fix but none of them was useful. Then i found the new function of "minimize memory usage" button,it is useful,but not so convenient.Can you please add a new way to use this function? Like: set a number of memory usage(for example 256000KB),when reach this number trigger the "minimize memory usage".Then it will be like "auto minimize memory usage". Or,you can just set an UI button on the toolbar to trigger "minimize memory usage".

Please check my screenshot Pic1:It's the live-stream tab,memory usage 1800+MB Pic2:But it seems not so large in "about:performance"

I've got about 10 bookmarks with links to support pages each about adjusting specific about:config setting to my needs. My job also requires me to change systems lots of times, from Mac to windows to Linux. Is there an easy way I can save my personal about:config changes to a file for easy import on other systems?

Thanks

Hi,

I hope you are well.

I have set up 11 custom devices that max the min and max sizes of bootstrap grid system (xs-min-360w, xs-max-575, etc) to aid me with checking my website on various screen sizes. Is there anyway to export this list or better still to synch them with my Firefox account so I don't lose these settings?

I am using Firefox Developer Edition (101.0b6 (64-bit)) on Ubuntu 20.04.

Many thanks Kaz

I can't open Firefox. When I click on the icon Bing shows up. I downloaded the latest version of Firefox, I can't install it because I get the message that I have to close Firefox because it is running. How can it be? I haven't been able to open it for weeks.

Hello,

Currently running MacOS Montery but the problem was still occurring on previous versions.

Whenever I use the green top left button to enter full-screen, the app immediately freezes and either crashes or has to be manually force quit. There are no reports in about:crashes and I there has been no success with troubleshooting mode or switching versions of the Firefox application.

Machine Info: MacBook Pro (16-inch, 2019) Processor: 2.6 GHz 6-Core Intel Core i7 Memory: 16 GB 2667 MHz DDR4 Graphics: Intel UHD Graphics 630 1536 MB

Any help towards a solution would be appreciated. Thanks!

Good day,

Really happy to see that mozilla is tightening up security. But unfortunately, I can't enroll into Two-Step Authentication everytime I enter code it's not being accepted. I tried multiple android apps of those codes and non of them work for me.

Because of that, I lost access to addons.mozilla.com account, because system doesn't let me in without 2step auth enabled.

Any chance I can use yubikey's intead of those auth apps? or anything else I can do?

if there's not already an option to autohide the bookmarks toolbar (like the address bar and tabs when in F11 mode [fullscreen])

can there be?

so like, on default the bookmark toolbar wouldn't show, but when I move my mouse into the specified area it appears (with the same animation as f11 mode)

 thank you,

let me know if i can already do that and if I'm just dumb.

 just to be clear, I want the tabs and url/address bar and tabs to always be there.

Actually might be cool to have options to autohide the tab bar too (separately).

 thanks again,

graham

tldr lol

Greetings. I can't open most sites I usually visit (even google.com) via my Firefox 98.0a1. This happens since today. All error codes are SEC_ERROR_LIBRARY_FAILURE.

Tried to:

• Disable DNS-over-HTTPS.
• Disable HTTP/3.
• Disable proxy (never had it enabled anyway).
• Disable sending info to Firefox developers.
• Change settings of DNS-over-HTTPS.
• Restart the browser (after each action).

Nothing helps me... But I still can visit some websites, but most common resources are not working for me. Please help me because I can't use Microsoft Edge without getting mentally ill. :/

Hello Everyone,

After inserting the proxy information, webpages in the container tab refuse to load/connect, I insert the IP address and I've also tried the Fully qualified domain name, using the type://host:port syntax, I get "The proxy server is refusing connections" and "The connection has timed out" error messages.

If I setup the proxy via the settings menu the entire browser uses the proxy server address, I am trying to specify a different proxy server for each container.

Please help me.....
