How do I block the 'You are seeing this message because ad or script blocking software is interfering with this page. Disable any ad or script blocking software, then reload this page.' ?

I have been using ublock origin add-on for years without any issues. For the past few weeks, pop up videos as well as above alert message appears on several news sites. Is this a glitch with the add-on or firefox browser issues?

Many thanks!

I can no longer access articles in vanityfair using firefox browser although edge works nicely. This is the error message I get:

"The page isn’t redirecting properly

An error occurred during a connection to www.vanityfair.com.

   This problem can sometimes be caused by disabling or refusing to accept cookies."

I haven't disabled or refused to accept cookies and I can't find the answer on Firefox website.

My Password manager signs me out everytime I close Firefox. I'm pretty sure its a privacy setting or something in the Firefox app and not the extension, as the extension works on my other PC and I found no such setting in the extension. Does anyone have a Idea what setting this might be?

I've been using my company website for many years without issue. Now all of a sudden the sign in page won't load. If it does and I do sign in, I have sign in issues with all sites under the main login. I use this almost every day so it's a major problem for me.

When I try to login into the mozilla addons using my firefox account it showing me the 2 factor authentication setup when I click the cancel button It suddenly takes me to the previous and when I try to create 2 factor authentication setup and I also Installed the authenticator app in the my android mobile which was google authenticator and I scan the QR code it gives me a code but when I try to enter the code it throws me an error it was an invalid code but I enter the correct code each time it stills shows me the same error please help me to login meinto the mozilla addons I need to update my addons ASAP.

I'm working on a web app and need to be able to test it locally. Firefox has no decided to allow only HTTPS when trying to access this specific app. I have tried removing it from history, but it makes no difference. I've restarted Firefox, I've restarted the machine. Nothing seems to work. Typing in "http://localhost<remainder of URL>" does not work, Firefox simply changes my explicit request for HTTP to HTTPS and access to the site fails.

This is not a general setting. I have other web apps I've been working on that are all accessible in Firefox and are being accessed using HTTP rather than HTTPS. It seems that Firefox has selected this specific app. In particular, HTTPS-only mode is obviously not enabled.

How do I get Firefox to accept that when I type in HTTP://... that I actually mean HTTP://... and not HTTPS://...?

I recently made a custom profile on firefox, and now some frames won't load. they appear as grey and white checkered boxes with the url linked inside of it. I've been trying to fix this for a bit now, and can't figure it out. Anyone know what's happening?

I am trying to run firefox unofficially run a windows vista Virtual Machine using the Windows Vista Extended Kernel, but is says the the dll "api-ms-win-core-sysinfo-l1-1-0.dll" is missing. It did this a couple of times and i was able to copy over all other dlls, but after placing this one in Windows,System32,Program Files/Mozilla Firefox and SysWOW64 and re-registering it, it still gives me an error. Could you please provide the location of the required dll since it can't find it.

Can't use Firefox to access make an appointment page: https://myappt.sdil.net/#/ Had to use Chrome (ugh!). Uploaded the Chrome page, but can't even upload the screenshot of the Firefox page (it's totally black) because the upload just spins when I try to upload it here!

Thanks for any help (or fixing whatever the problem is with Firefox)!

Ik heb een vraag ?

Als ik mijn Firefox twee x open, en dan weer beide sluit zijn de volgende x als ik mijn Firefox open al me tabbladen in eens weg en moet ik ze opnieuw vast zetten.

Hoe kan ik het zo in stellen ook al open in 100x Firefox en weer sluit dat hij de Tabbladen onthoud en dat ik ze niet steeds opnieuw moet vast maken ?

Met vriendelijke groet

Whenever I open Firefox on my Windows 11 laptop, a notification panel appears bottom right highlighting a news article from cordbusters.co.uk. I don't remember subscribing to this service and I can't turn it off. I can ignore it, and it times out after a few seconds. I checked addons and extensions but searching for 'cordbuster' in Settings gives no results. Running an internet search for cordbuster gives results for other sites quoting cordbuster but nothing suggesting a service provision. I am a long-term user of Firefox on phone and laptop.

For the last month or so I have had problems with Firefox using too much CPU, too much memory. This is not long after I have restarted. It soon gets so bad that there is a 3-6 second delay in anything I do. At this point I am going to have to stop using FF as it is too disruptive. Cannot place any other system changes.

Hi, I'm developing a webapp that's designed for print. It uses a "pinterest style" layout to have a column grid of objects with variable heights, and the print styles avoid breaking these items over the page barrier. (In fact, there are two grids on the page, one after the other). The website looks and works fine on screen, and both screen and print work great on Chromium browsers. But on Firefox, using ctrl+P or developer tools' print view causes the page to hang and the tab to ultimately crash.

I know it has something to do with handling the grid layout CSS as the print preview worked fine until I made the change from a traditional row-grid to a column-grid.

The site creates a variable amount of content based on user options at the top of the page. If the content generated is quite small (avoiding a page break?), the print preview works fine. In the link below, I've included some GET variables to guarantee a long amount of content to reliably reproduce the issue.

The site in question.

when i click on a firefox tab it opens in a new window - how do I stop this?

Already tried going about:config and changing 'browser.tabs.allowTabDetach`, and set its value to `false` and it is not working. Advise.
