Firefox-Hilfeforum

Hello Mozilla, I like your picture-in-picture feature in Firefox. Is it possible to check via JavaScript if a user has PIP enabled? Some events like "enterpictureinpicture" are described on your website https://developer.mozilla.org/en-US/docs/Web/API/Picture-in-Picture_API, but have not yet been implemented. When will this happen? It is important for web designers to know whether a visitor uses this feature - for example to hide the original video. Or is there another method to hide it?

Spell check doesn't work at all. It doesn't show incorrectly spelled words, and there's nothing in the write click menu in text areas. I have it turned on in settings, and I have a dictionary installed.

I'm using a new laptop so everything is a fresh install. A few of the newsletters I've signed up for are now using GetResponse for their marketing. Any link I click on in these emails leads me to a "The page you're looking for doesn't exist" error 404. No matter what I try (disabling all extensions & setting Firefox's config setting 'extensions.blocklist.enabled' to false). Both of the companies that send the newsletters as well as GetResponse don't really seem to care and just blame Firefox. Can anyone help me fix this... if in fact it's something on my laptop that's creating the issue? I only use Firefox browser... nothing else and would hate to starting using some unsafe browser just to access these links. Thanks.

I've just rebooted and I've lost two windows with thirty tabs, or something.

When I started Firefox, there's nothing in the Recently Closed [Tabs, Windows]

Reading online, I see that Firefox should be writing some files to the sessionstore-backup directory, like these:

recovery.jsonlz4: the windows and tabs in your currently live Firefox session (or, if Firefox crashed at the last shutdown and is still closed, your last session) recovery.baklz4: a backup copy of recovery.jsonlz4 previous.jsonlz4: the windows and tabs in your last Firefox session upgrade.jsonlz4-build_id: the windows and tabs in the Firefox session that was live at the time of your last update

, but I only find recovery.jsonlz4 and recovery.baklz4 and both are tracking current time, which means they are getting data from the currently opened Firefox.

These are the only files I find in this directory.

Where are the other files supposed to have gone?

My [[website|https://pestopgroup.com.au/]] is not working properly on firefox. Please, take a look and help me in resolving my issue. Thanks!

I usually use DuckDuckGo for searches. Since the last Firefox update, I get a popup ad for a "DuckDuckGo Privacy Essentials" add-on every time I (a) re-open Firefox and (b) search with DuckDuckGo. How can I stop this?

Thanks in advance for your help.

I am using Widows7 Home Premium with Yahoo Mail and Firefox, a combination that's worked for years.

When starting an email and when you put the first letter in the 'To' line I used to get a box suggesting all the names in my contact list beginning with the same letter. With a simple click on the name you want, it appears on the 'To' line. This is not now happening and it's a pain having to dig out email addresses from elsewhere.

I have not made any alterations anywhere on the computer, it just disappeared one day.

How can I get this feature to reappear?

I have a question for y'all. I checked my Firefox about firefox and it says I have the most recent 78.2.Oesr (64-bit). So is it telling the truth that I have the most recent becasuse You Tube is saying I need to update my firefox?

With the last 2 updates, my bookmarks have not been reinstated on the bookmarks toolbar. They are listed under "Bookmarks"; how do I get them on to the Toolbar again? I am using version 104.0.2 (64 bit)

Whenever I try to type in numbers on a web page, Firefox either closes the page or it opens the address bar on the browser. Sometimes it puts up a dialog box asking if I want to leave the page. It's very frustrating because Firefox is making it difficult to add a new credit card to my accounts. This started in the last few weeks, and I'm not aware of any new updates. I tried to refresh Firefox but this problem is continuing. I have a refurbished by Apple 2020 MacBook Pro running Monterey 12.4. I believe in Mozilla and would hate to go to Chrome as my main browser. Can you help me? [email removed from public]

I'm using a 2021 macbook air and cannot find a way to change the font size of anything in the Firefox toolbar. Not the bookmark folders in the toolbar, url address bar or tabs. The default is a microfont that is hard to read for some of us. The old add-on is no longer useful, and one other suggestion I was able to find involved changing the settings in configsys. That is an absurd solution for someone not familiar with changing code or intimidated by the process. I'd love to know if there is an easier solution that I'm missing here. And if not ...why?!
