My primary email account is my companies email. I no longer work at that company and do not have access to that email account.

When I attempt to change email to my personal, which is listed in the account, it requires that I enter a verification code that is sent to the current primary email.

Is there a work around for this, or should I delete the entire account and start again?

As far as I know there are quite a few keyboard shortcuts one can use in picture-in-picture mode. However, they don't always work for me. Most notably, spacebar often toggles the last thing I clicked in picture-in-picture mode. For example, I enter full screen mode and press spacebar to play the video, but instead it exits the full screen. Or I click on one of the "rewind" buttons, after which spacebar adopts the function of that button until I manually click play. For some reason, the arrow keys also don't always work. I suspect it's the problem of the same origin.

I also feel the need to say that this behavior is not limited to picture-in-picture. This is similar to what happens in almost all video players online and, possibly, some of the offline ones as well. I have also checked a few forums (VLC development thread and Stack Overflow) and it seems to be a common issue across many video players.

Still, if anyone knows any way to deal with this problem in Firefox picture-in-picture as a user, I would greatly appreciate it, as it interferes with multitasking a lot more than on any other players.

I have exported bookmarks in XML en went on a well deserved vacation. At my holiday address I found out that there is no possibility to import the created XML-file.

It doesn't make sense that Firefox only supports the export, not the import!

What to do now?

Windows 10 Firefox 116.0.3

Hi I am getting this message when trying to view the `preview` of an item that I am listing on the ebay site.....Firefox Can’t Open This Page

`To protect your security, signin.ebay.co.uk will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.`

I have no idea what this means? but I cannot see the preview on ebay. Everything is up to date and was working a few days ago. Thank you.

Firefox is slowing my computer to a snails pace. Your "help" page said to go to about:config. I don't know where to find about:config. Your software doesn't say where to look for it or a place to look for it. Your help is no help at all. I don't have time to look at forums that in my 25 years of using computers I have never found an answer to a problem I have had in forums.

I used to have the Tab Mix Plus extension which no longer works in Firefox.

The one feature I really miss from this extension is the ability to alternate between 2 tabs by clicking on one of them. I know that there are various extensions that allow you to switch tabs using shortcut keys and I do use the Switch to Previous Active Tab extension which is useful but I do miss the simplicity of being able to just click on a tab to switch to the previous and even after several years without it I still often try to do it, forgetting that it no longer works.

Is there any extension or setting that can reinstate this feature?

Did the originator of the video change how they are recording or did Firefox change? I now get a different window when I access the video and use shift + R click. Instead of a choice of save as, I get save page as; save page to pocket; select all; take screenshot; view page source and inspect. thanks

Hello all,

I've recently switched back from Chrome to Firefox, imported all passwords, bookmarks etc and off I go...

Only, I'm coming across more and more websites (about four so far) that don't have their logins transferred. The most recent and big one being Twitter, where there are two accounts saved on Chrome, but Firefox says it has none. I've tried all the usual, restarting both browsers and PC, checking there's no security I can find that locks those down (if there is I cannot find it) and the like. I'm on Windows 10 Pro, fully updated with latest patches on all browsers and Win10 itself.

Is this a security thing from those specific sites? Could it be a drastic change to the address fooling Firefox (and if so, why if I go back to Chrome do they load in fine?) or something I'm just not thinking of? I'm really hoping I don't have to keep going back to Chrome randomly to find a password when Firefox finds one it doesn't remember, kind of destroys the purpose of moving away from Google...

Thanks in advance!

Not sure what's going on, but when I am on YouTube this happens and nothing loads at all. The website is working on Edge and so I think it's YouTube angry that I have ad blocking enabled. Any advice

How can I recover the history that has been deleted from firefox? Already there is an article from 2020 which says to find index.dat file but there is no .dat file that i can find. I am looking for the file in the following location: AppData\Local\Mozilla\Firefox\Profiles\83ctti6r.default-release\cache2 and that location is the only one with a file named index but it is without .dat extension. If that is supposed to be the file that I am to use then which .dat file reader do I use to open it and recover the history.

My M-1 MacBook Pro has been running warm since I installed Firefox 116.0.3 (64-bit).

EtreCheck Pro reports that "plug-in container.app" is a runaway process.

When I show package contents for Firefox, I can see "plug-in container.app" in the MacOS folder.

Will there be an update soon to correct this problem? Firefox is my primary browser. I work in the SaaS industry and have to run a browser 24/7.

There are old website addresses stored somewhere in Firefox for sites that no longer exist, how can I edit / remove those from FireFox. Using FireFox for LinuxMint 116.0.3 64 bit

All videos not working in my firefox youtube get An error occurred. Please try again later. (Playback ID: BJCeW3LUpJkeHgq-)

and netflix get like image i send

i do not know why please help me

hi i've been using firefox for several years now i recently started getting an issue where the pages will not load at all, or won't fully load for a few seconds (like 30 seconds) this results in timeout error or just endless loading icon. if the page does load, it will not load completely and miss out a lot of info. for example sometimes when i go to youtube, all i see is gray squares instead of thumbnails. this doesn't happen ALL the time, but it happens very very often. refreshing several times fixes the issue. usually when this happens i try to quickly go to incognito and launch the website on chrome simultaneously, and it only loads instantly on chrome.

things i've already tried: -disabling extensions -clearing cache and cookies -incognito -removing ALL cookies -reinstalling firefox -changing DNS to google and cloudflare

i'm very frustrated by this. i don't want to discontinue to use firefox, i hate chrome. please help

About 3 weeks ago I started getting this pop up box randomly appear. It coincides with high CPU usage and will generate multiple boxes shingled on top of each other. What is it and how do I fix it? I've tried multiple online guides but nothing seems to work. Thanks.
