My e-mail will not load sub links. It pops up a list of links not related to the e-mail. Stated when I installed avast. Took avast off. DID NOT fix problem. What now???

I cannot access my Coventry Building Society account online using Firefox. The building society says it is is due to a recent Firefox update being insecure. Can Firefox fix this?!

Ever since I updated last week, one website that I use will not work. Whenever I try to log in to the M&T Online Banking website, it blocks me and says "M&T Online Banking Is Temporarily Unavailable." The app works on my phone and I can log in through Chrome, it's only on Firefox that I'm getting this problem. I called M&T Bank and they confirmed that it's a problem with Firefox. Something is blocking me but I don't know what it is. I am not using a VPN or adblocker.

The icons on my home page suddenly became significantly reduced in size. Sure, I can tell what they are, and I've increased the text size for their identifiers below the icons. But they are now so small as to be not pleasing to the eye. How can I put them back the way they wuz?

My Firefox browser has been crashing for a while now (Years). It's fine playing YouTube and BBC iPlayer but when I advance the time marker to a different part of the stream or video, it crashes. It also has a problem when playing slots. It seems to crash a lot making it impossible to play.

I have tried using Firefox in Troubleshooting Mode but the same things happen.

Here's the crash report ID

Many thanks in anticipation and I hope someone can help me fix these issues.

How do I get the PDF viewer to work again? For years I have used the setting "save" to automatically download. Now I am unable to view them without going in and changing the settings to "open in firefox". I would like to continue to use the save setting without having to constantly change this back and forth. When I click to open the file, all it does it grey out.

When I try to compose a new email, or reply to one, the pane opens to compose the email, but immediately closes before I can enter anything, reverting back to the Inbox. A new, empty draft gets created. But there is no way I can create a new email. Problem does not occur on other browsers. If I open a "New Private Window" and sign in to Outlook, I can then create the email there, but after a while the same problem occurs in that window too. Tried clearing Firefox cache temp files and cookies, but that did not resolve the problem. Using web based Outlook, Windows 10. Firefox is up to date.

Any suggestions?

Customization:

I want to change the Microsoft desktop icons on shortcuts to a number of internet URLs. Unlike with other shortcuts, this is not possible with Firefox. Too many of the same icon are confusing. Seems to me it would be a simple and useful option.

Hi, In the last hour FF has stopped working completely. I made the mistake of using Ccleaner, which is probably the problem, I haven't had issues cleaning before, though I usually check the registry before deleting and don't recall seeing any entry for Mozilla (I may be wrong, though).

Firefox was working fine a couple of hours ago, but now it won't open at all, except in admin mode and then it won't open any links or tabs, not even settings. I've uninstalled FF, deleted the folder in the Programs folder, and reinstalled it from scratch, but there is no change (the one difference is that it wouldn't open in Admin after before I reinstalled it). Waterfox doesn't open either, but Thunderbird seems to work with no problems.

Thanks, Matt

does Firefox no longer support sites like The Guardian, like the Atlantic, other news outlets. it never lets me sign in but returns to the home page after signing in with email and password. What do I do?

I have check spelling enabled in Firefox. I use Firefox in English for technical reasons, but I write most of my emails in Hungarian. I was prompted to install a dictionary addon to be able to use Hungarian spell checking. I did install that addon, however I still can not choose any other language to spell check in but English. I would like to resolve this issue. My Firefox installation is very fresh, I am leaving Chrome in favor of Firefox and would like to stay. What I would have expected is that I install Hungarian, then the spell checker automatically identifies the language pack it needs to use.

Every time I try to view a pdf file on Firefox I can view the file but in the lower right 1/4 of the screen I get a graphic of a page with shaded areas representing lines with writing on them. There is a type of pen cursor moving along the line.

This happens with different pdfs - from the internet and from my saved files. This doesn't happen on another computer with Firefox.

I've deleted and redownloaded Firefox an number of times, also tried troubleshoot mode - no improvement. Virus scanned, restarted a number of times.

Pdfs work on edge and chrome and reader with no problem.

I have a screenshot.

Any Ideas? Thanks

For the past month or so, I'd say about 20% of the websites I visit using Firefox just show a blank, white screen. (See allbirds.com site image attached for example.)

1. Cleared the cache and cookies to see if that fixed it. It didn't. 2. Entered Troubleshoot Mode to see if that fixed it. It didn't. 3. Disabled all extensions to see if that fixed it. It didn't. 4. Disabled "recommended performance settings" and hardware acceleration--in combination with some of the above--to see if that fixed it. It didn't. 5. Reinstalled Firefox to see if that fixed it. It didn't. 6. Also paused/disabled VPN (Nord) and anti-virus (McAfee) to see if that made a difference. It didn't.

Any other ideas?

Thanks.

I can't find a place to control third party cookies in the Security section. I used to be able to donate on my church's website but now it doesn't work. I tried doing it with Microsoft Edge and it worked fine. I hate to erase all my history and cookies because it takes away log-in info on my regular websites. Any ideas? Thanks for your help Terri

I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.
