Hi,

I cannot seem to close a tab, usually the last one I opened, in my browser window. It remains at the upper left hand corner of the browser. Please note the tab in the attached image.

How do I close this window and prevent this behavior again?

Many thanks,

Lisa D

I've been using FF since release #3 and like it a lot since I cut my teeth using NetScape. The past few days FF will not open one of my email accounts. When I click on login, it brings up the logging on page and then just starts blinking and will not sign me on. If I use MS Edge to sign on it works fine. The email account has been working fine for many years so don't know what to do. I've deleted recent history, but that does not help. Any ideas will be appreciated as I like FF and don't like to have to use two different browsers to do my daily tasks. Thanks in advance for any help you can suggest. I'm currently using release 131.0.3 with W-10 on a desk top PC with DSL from my phone company with the email account with their ID. My phone company does no know about or support FF.

When I load PBS.org I get a message that PBS is having connectivity issues. I can load it on Safari without any problems (and my Kindle too). Is this Firefox or PBS's problem? Please help.

In the last few days, the common Cloudflare widget required to login to many web sites has abruptly stopped functioning in my browser. I'm trying to diagnose what's caused it. I'd appreciate any suggestions or advice.

I noticed the issue on nexusmods.com, but I've confirmed it's a universal problem on ANY site that uses Cloudflare protection. I've continued to use Nexus as my test case.

Observed behavior: 1) The Cloudflare widget loads 2) It displays a checkbox noted, "verify you are human." 3) I click the checkbox. 4) It immediately begins "thinking" (spinny circle and "verifying...") for about nine seconds. There is an "error" message that appears during this, but no details are offered (see screenshot) 5) The widget reloads. 6) Go to step 2

This is an infinite loop.

Fixes attempted: - Disabling all extensions (uBlock, NoScript, Privacy Badger, Decentraleyes) - Clearing cache - Updating to the most recent FF build - Accessing in a private window - Changing DNS settings from Cloudflare to NextDNS - Disabling DNS over HTTPS altogether - Disabling HTTPS-only mode

Firefox has stopped obeying target="_blank"

Started a month or so ago.

Take a look at Firefox target="_blank" problem for details.

There is not a topic in the dropdown list that remotely addresses this issue so I just selected Performance and Connectivity for the hell of it.

I have a HUGE problem with Firefox memory usage. Some open instances of firefox are taking anywhere from 600mb to 2.8gb of memory. Since firefox opens MANY instances even with only ONE active window, this very quickly uses all available memory (4gb) causing a full laptop crash.

More concerning is that CLOSING the worst instance of memory usage STILL leaves the single open page/tab open, so what exactly was the memory eating instance actually doing ???

I have included a screengrab of the many remaining instances of firefox in windows task manager AFTER closing the main culprit.

I have also included a screengrab of all the adblockers I use which I believed would limit unnecessary memory usage, but does not seem to be effective.

Many Thanks

On some websites, such as scratch.mit.edu, the fonts have been displaying as Burbank Big (a font i recently downloaded) instead of the regular font. This happens on other websites that don't use Helvetica Niue as well, so i'm stumped. I checked the styles panel in inspector and it showed the correct names, but when i hovered my cursor over it, it showed a preview of Burbank Big instead. What do i do to fix this?

Anybody. I'm ending up with dozens of tabs open because: 1. every time I hit HOME on my work tab, a new tab open up. One after another. It doesn't take long to have dozens of tabs open. Can anybody help me out here?

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.

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 use a program called "URL Manager Pro" on the Mac to manage my bookmarks in all my browsers. Double clicking on a bookmark icon in URL Manager can open the URL in a new tab, the same tab, or a new window depending upon how I set the preferences in URL Manager Pro. This works fine in Safari. However, in Firefox, the website opens in a new tab regardless of how I set my preferences in URL Manager.

The author of URL Manager tells me the issue is a problem with how Firefox deals with AppleEvents. It's very annoying to accumulate so many unintended new tabs and then manually close them. Is this fixable in Firefox or is there a work around?

Thanks

I have a Dropbox Paper document that I use for my bookmarks. It lists the name of the site (with link attached) and hints as to my username/password for any given site I use.

For years, it has worked just fine, but trying to solve a different problem, something happened (in my settings?) that renders those hyperlinks non-working. When I click on, say Facebook, it formerly took me right to FB. NOW it gives me a weird yellow box in the upper right corner that says "about:blank" in the upper left of the box, and 3 white boxes at the lower right of the yellow box "Allow" "Deny" "Close." If I click on "Allow," I get a blank page. My navigation doesn't seem to recognize the links I've placed in the Doc.

A friend on FB posted a link to a YouTube video and when I clicked on that, I got the yellow box with the proper URL and a white box option to continue. I've tried to recreate that particular box, but, apparently, once it's accepted, it's OK from there on out.

I have tried deleting the link from the Paper Doc and reinstating it, and I still get the yellow box.

What have I done and how the heck do I get rid of that yellow box?

Hi, Nvidia RTX Video HDR and Super Resolution works fine when I open a link. But if I scroll the page it turn off. The video still play but the colors changes, I can see that RTX enhencement is then inactive on the nvidia panel. Sometime immediately sometimes after more scrolling. Same on Youtube and Twitch. Any Idea ?

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.

Hi, It is not a question but a bug report. From the version 131 up today the Nightly stopped to initialize quickly as before. Certainly, it is not the windows 10 21H2, the antivirus, the firewall or anything other similar internal problem, just because the Edge and the Opera are working fine and they are four times more rapid than the Nightly. It is just to say, that your procedures to improve the security is transforming the Firefox in a mirror of the usefulness Chrome. I take the time to open the home page of Firefox = 9 seconds, against 0.28 s of the Opera. So, I think you should rethink the security and other hidden setting options of the Nightly, because as is, it is very bad. The big thing that the Geeks from silicon Valley did not have in mind is: There are lot of people that need to find extremely fast a configuration, like to export/import passwords from older browsers, or computers, without need to replace one by one. There are many other things that you decided to hide, but I don't know why. Anyway, I will try to update one more time, then, unfortunately I could not use the Firefox anymore. Further, I want a few add-ons, either if there is any percentage of insecurity. A few times we need afford risks to understand and discovery other problems in the web. We cannot do it anymore with the Nightly.

Trivial example of "weird" behaviour:

I have an Adobe Reader window open and a Google Chrome window open on my screen. I click on Firefox to open another window and both the Adobe and the Chrome windows are removed from my screen. No tiling. Just moved away. I can get the Adobe and/or Chrome window back, but then Firefox "disappears." This makes Firefox unusable for me. I have NOT changed any of my Firefox settings in probably years. Help please.

Hello!

A very important email folder in my Thunderbird just vanished. I didn't touch anything! My email was downloading very slowly and so I closed the entire Thunderbird application. When I re-opened it, the folder was gone. Everything else is there as before - all other folders, my inbox etc.

I have no idea what happened or where the folder went. I can't find anything online that addresses the problem or how to solve it. I'm very much a tech novice. I need a solution that a 5 year old could navigate lol

S.O.S. Cara
