Firefox Support Forum

After the last update to Firefox on my Mac Book Pro running Mac-OS Monterey, I was offered an update to Ad Block Plus. This add-on, AdBlocker Ultimate shows as installed but it won't run at all and shows as disabled and my existing AdBlock Plus quits working. I'm using Adblock Plus on my windows based computers with all synced together with the Mac Book and the Windows computers are OK, but not the Mac Book. Is there any way to get my Mac Book working correctly? In addition the last update to Firefox on the Mac Book opens by offering me "Life in Color" every time it starts up. How long do I have to tell it I'm not interested? Thanks for your help.

In the last few days, I started having multiple web sites blocked with "SEC_ERROR_REVOKED_CERTIFICATE". They work fine with Google Chrome and Microsoft Edge, and I trust them. One example is http://www.wumb.org, a public radio station. I found nothing in Firefox Help to bypass this security flag and go to the page.

If there is a work-around, please make it show up when searching for SEC_ERROR_REVOKED_CERTIFICATE in Firefox Help. If there is no work-around, please add one. Otherwise, Firefox, my favorite browser, will quickly get a bad reputation.

Thanks,

Opening up firefox last week am a message saying something was wrong/couldn't proceed (I don't remember the exact text). I tried to delete the message, but it just came back every time blocking opening firefox. I tried to restart it, but the same blocking message reappeared. I then uninstalled it and all my files disappeared, of course. I've today reinstalled it, but no history, etc.. How can I get my original web files back? Do you have a 30 day grace period where any file can be restored like the one Microsoft has? Can I get my webfiles back at all? Please help. tmr W10 64bit

Since upgrading to FF 94.0.2, I cannot logon to Chase Online Banking. The site texts me a code which I then enter and receive a message that part of the site does not seem to be working. If I use Edge, I can get in without a problem. I went into troubleshooting mode and it let me logon without a problem, but returning to normal mode repeats the problem. Using private mode does not work either. I'm not sure what is going on here and any suggestions would be appreciated.

I had a similar problem last year when an auto update came through. After several suggestions didn't help I opted to reinstall a previous version and upgrade that. Now it's back again with the v94 update.

I've disabled ALL extensions. No help. Themes don't seem to make a difference. However, when I went to about:config and entered "toolkit.legacyUserProfileCustomizations.stylesheets" to make it true to allow chrome.css files to work it began immediately. Reset it to false and "X"s are back. Set config to TRUE and it screws up the "X"s. Again, all this is with all extensions off.

I hate the transparency of the tabs and menu bars so I need to set .css files. How else can I do it?

how to keep browser from resizing after shutdown? oversized by 20% on restart , happened last night after a uneventful cpu shutdown, upon restart this morning cpu windows enlarged to "large icons" those were reset, open firefox it to was enlarged, reset to 80% zoom , but it will not stay 100% size is NOT 100% size i want or had, how to set so it will stay...and why did it change in first place "on its own" thanx for your help...vic

I have recently updated directly from v89 to v92.0.2. Since then, I do not have the task manager option in the dropdown menu > More tools. Screenshot attached shows what I mean. This issue does not exist on a new profile if I were to make one, but I am trying my best to avoid transferring everything to a new profile if I have to.

If the only solution is to indeed use a new profile, I would like to know if there's a way to transfer addons and their settings through file copying and pasting.

Thank you for the help!

So i wanted to forget about this one website because it keeps automatically recommending it to me because of my browser history for it. i just want to go to this bookmarked site but it ALWAYS goes to the one thats in my history. i clicked "forget about this site" yet it still pops up. please help.

My firefox browser has had issues displaying fonts when I have the "Allow pages to choose their own fonts, instead of your selections above" box checked. Its not all webpages as some have more bolded fonts, but it is more than one site.

I have scoured these forums trying to locate an answer, but for some reason the fonts are still so thin and unreadable. I have even erased all existence of firefox from my computer and reinstalled, but the issue still remains.

Please help me.

When I try to post a pic on Marketplace in Firefox I select the .JPG picture and upload it. The picture I want to post appears fine before I upload it. Once I upload it to Facebook, it just appears as a solid colour. I have attached a couple pics, one is of the pic I want to upload and the other is the pic after it is uploaded. I should state that if I use Chrome or Edge, it works fine. And if I try to post a pic to my timeline it works fine. I just have this problem when using FireFox and trying to post to MarketPlace I know, well just use Chrome or Edge, I DON'T WANT TO :-) I want to use my FireFox. Ian

I have cleared out site and cookie history with no success, How do I eliminate this error. Other browsers have no problem with accessing the Spectrum TV app on this windows pc.

My new computer is running Windows 11. I just tried to log on to my Vanguard account and the Logon button has no response. Using Microsoft Edge I had no problems logging on so the issue must be with Firefox security controls. I have turned off Ad Blocker Ultimate as well as made an exception for cookies from this site. What can I do to fix this?

Hi I accepted the popup notice that a newer version of Firefox was available - while doing other things. When I next opened Firefox, all my profile was gone. No folders, no bookmarks, no extensions, it appears like a virgin install. How do I get my profile back??? Firefox 94.0.2 Windows 10 Home Desktop PC

I want to transfer a Firefox profile from my old computer to a new computer. The online info has been distinctly unhelpful. I copied the profile from my old computer put it in the Profiles folder on my new computer but FIREFOX does not notice it. What is the problem?

That ugly man in the browser won't let me enter websites or pages within the website ,like sweepstakes entries on Cabela's website for example. My numbers are [phone number]. Michael Lodsin When I open Firefox, there are 3 or 4 blue screens pop up to make excutible orders to my computer, I always click them off. but they we not always there. Is someone using my computer from afar, or worse tracking my keystrokes or monitoring me ?

I no longer have sound on any websites after I muted sound for 5 minutes then enabled it again. I have uninstalled and re-installed Firefox, checked the settings and done all the tips provided to no avail, I still have no sound

I use a Firefox account on two different machines- one is a Mac and the other is a Windows machine. I have some programs installed on the Windows machine that installed an extension for Firefox. Those programs are not Mac compatible but because of the same account, those extensions were copied to the Firefox installation on Mac. I was wondering if there is a way to isolate the extensions to just the windows installation? Thanks!

I must log in to the WiFi network I use. When I start FireFox the first time, it brings up my login page, I click [Accept], and I'm online. After a while on, I get kicked off, and must log in again. (The non-internet, WiFi connection remains active; but I'm neither logged in nor online.) How do I re-initialize the automatic login function ("detectportal"?)?

Closing, and re-starting FireFox again doesn't work; it initially tries to go to my homepage instead... *but it can't*, because I'm not online. I can't go to the login page's displayed URL, for the same reason. I have to actually restart the computer, loosing whatever I'm doing, then start FireFox. Then, and only then, can I get it to go to the network login page so I can login and continue.

Is there a button, "about:thingie", or setting I can use to reinitialize the automatic login page search & display mechanism? Rebooting the whole computer is a xxxx.

Is there any way to set an exception? I keep getting an error on this totally legit website -- and of course Microsoft isn't going to offer me any solutions other than to use Edge (which works)

This web site ' cornerstonegrp.securecafe.com/residentservices/carolina-club/userlogin.aspx'. The site tells me that password or pass code incorrect. In the past allowed me to continue to the main web page. At this time all of the add-ons are disabled. Cornerstone web site is the only site not recognizing login. Please help.
