I get this when trying to get my email from Comcast:

How do I remove the scam pop-up that won't let me access firefox on my iphone? The pop-up says "your apple iphone is severely damaged." I can't open a new tab or delete the current tab.

The only icons I can see on the right hand side of my toolbar is the NoScript icon, along with the Save to Pocket, FF Account, Extensions and hamburger buttons.

I should have about 12.

I just installed a new system, launched FF and set it up to sync with my account. Everything else appears to run fine - passwords, history, etc. The Tree Style Tab works fine too.

I have double checked the other solutions I found here, such as private viewing options, or trying to find the icons in the customize screen, but that's not the issue.

My other FF instances on other machines are still fine.

I just updated FF on this problem machine to 115.0.2 but no joy.

Is it possible to permanently set a different search engine for private browsing? I have Google set as my search engine in my normal browsing mode, but I'd like the private browser search engine to be permanently set to DuckDuckGo.

(I realise I can manually set it each time to DuckDuckGo but this is tedious.)

With thanks.

So, whenever I open Firefox it will act normally and then after a second close by itself and when I reopen it, it will be in remote mode. I know how to fix this via about:config and do this every time, but I would much prefer a permanent fix, nothing else on Firefox or my computer indicates something else is going on, its just this. I've even at one point uninstalled and reinstalled Firefox and it didn't help.

just updated to 115.0.1 on the Mac yesterday and now tradingview website isn't working - i tried adding it as an exception in EnhancedTracking and CookieSiteData like i did with ebay to get it working again but no luck with tradingview... any ideas ? thx

This issue is so annoying, that I need to ask Firefox community what I can do. So, the problem is, that if I set custom home page called Infinity New Tab (Pro), then I will restart Firefox, then it reverts back to Firefox Home.

I think, that this is completely unrelated to malware, because I'm scanning my computer very often.

Are my preferences/settings corrupted?

However the Infinity New Tab (Pro) is no longer available in addons.mozilla.org, so if you need .xpi file, then tell me, and I will attach that file here.

On the Swedish newspaper site https://www.expressen.se they have videos in many of their articles all over the site. And for some strange reason I can't get any of their videos to play in my browser. Im using windows 10 64bit Home and version 115.0 of Firefox (64bit version). Both windows and firefox have the latest updates. The error I have looks like this: https://imgur.com/a/BK9WaOC

" THEOplayer workers could not be loaded. Please check that the worker's version matches THEOplayer's version (5.1.0)".

The link to that specific page is: https://www.expressen.se/tv/nyheter/har-staller-laman-upp-som-brollopsmarskalk

I have contacted the newspaper support and they responded they have nothing to do with the issue so it must be something with my browser settings or addons that causes the videos not to play. I have tested with all my addons disabled and I still get the same result.

However the same videos works perfect in Chrome and Edge browsers. I am clueless to what may cause this very disturbing issue because I love using Firefox as my main browser but now I'm forced to browse this newspaper in chrome instead to see the videos. Not a big issue though but still... I have never in my life heard of THEOplayer and thought it was something media companies use to show their videos on their sites etc.

Here is a sample URL that works on Microsoft Edge (current version) and receives an error message on Firefox (115.0.2): https://www.t-mobile.com/home-internet The error received from the web site when using FF is:

Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

FF was working with all T-Mobile pages a few months ago and now fails with this same error on most pages.

To test on Edge, I pasted the identical address that failed in FF into Edge and it worked fine so I am confident I am comparing the same web page on the two browsers.

Thanks for your help. Claude

Hey, this has been going on for a few days, but when I try to use twitter on desktop, there are no retweet/like/reply buttons. This problem doesn't exist on Chrome or the Mobile app. I can reply to things, but that's it. I also can't browse through my notifications without the page immediately displaying the "Something went wrong. Try reloading." message. I'm not sure what's causing this or if it's just me or what.

For a while now (can't remember when it started) rendered graphics and text on FF is fuzzy. Examples of this can be see on Google maps, Miro, Powerpoint etc. On Chrome, Edge etc the rendering is sharp at all zoom levels but in FF its fuzzy until you zoom in.

Viewing on a 4k monitor, running 115.0.2 (64-bit), using the Windows store install Hardware acceleration is turned on. Tested on multiple PCs, all Windows 11

Attached images which shows the comparison between Firefox and Edge Both browser windows are the same size and the default zoom (100%) Examples attached are for Miro and Powerpoint

So I'm using firefox on my old PC and want to export the login data to my new PC. Firefox has export passwords to CSV but there is no import CSV in firefox on the new PC. There's import HTML but... firefox exported to CSV not HTML so I'm really confused, why would it export to a format that cannot be import?

OK I am not sure this is a Firefox issue but my g-mail account is sending composed messages to the TRASH folder. I have been using Proton Mail and have a number of email address depending on who I am emailing

Tried a few changes to my g-mail account disabled IMAP and POP that did not work I have a number of blocked email address did not delete these

Is there a shortcut to deattach tabs from one browser window so it turns into seperate window, so that you don't need to deattach tabs with clicking and dragging them with mouse?

I am very happy with the upgraded Firefox library. It works great except for one feature. Maybe there is a setting for it that I have missed.

When I click on an item in my library to open it, it opens it over top of the right-most tab that I have open. That means I always have to be careful to have a blank tab open, otherwise I lose the last item I was viewing. Is there a setting, or can you add a setting, to have the library open links in a new tab, or if one prefers in the existing tab? I want to be able to open in new tabs.

I am receiving the message Did Not Connect: Potential Security Issue ... requires a secure connection ... when trying to access my Shopify website AngelFallsHomes.com. This ONLY happens with Firefox; all other browsers are working fine. What do I do to fix this because obviously it is a huge concern.

I cannot log into New York Times via Firefox - ms says it thinks my IP is a bot. Also blocked on a local newspaper Montreal Gazette. I am able to log in w/ no prob on Opera - please advise? thanks!

Hello

I'm trying to sign into a Microsoft 365 email account but can't get beyond a screen saying "To use this site, you need to change your browser settings to enable DOM storage or cookies."

I've enabled DOM storage and cookies but no difference. I've cleared cookies and no help. I'm running Firefox 115.0.2 and Linux Mint.

Is part of the problem that I hate Microsoft and they know it?

Thanks
