Firefox Support Forum

I added my own shortcuts and deleted all the preset ones (Wikipedia, Twitter, Amazon etc). On deleting the last one of the default ones, the 'Add a shortcut' button has completely disappeared. Is there another way to create a shortcut?

I am trying to view uploaded videos in to my work portal and when I try to view the video this is the error message I receive. I am running WIndows 10 on my desktop. My Windows is up to date and I have cleared all cookies and still not working. Please help. Thank you

I am using Firefox 127 on Ubuntu.

When I press the Control key, I often lose focus in the window I am currently viewing. This is annoying as it prevents me from copy-pasting for example.

Sometimes the focus is back when I release Control, sometimes it is lost and I have to click again on the text field. It does not happen on all websites, for example support.mozilla.org works well, but it happens on duckduckgo or overleaf.

It does not seem to be the same as existing issues such as [the "show mouse when press Ctrl" of Ubuntu] (it is disabled) or an addon (the problem still happens in safe mode).

In case it is useful, when I press Control the tab bar background goes slightly darker, see attached images.

Thanks for your help :) Nicolas

For two days will tab crash for TikTok. For years, will not allow access to certain sites and no contest entries for the last few months. Worked before. No phone help and to download the browser doesn't work. I was upset as won't load TIktok and I NEED IT as use it daily. Please fix it ASAP!! I wasted time contacting Monzilla, as was only link for Firefox. They told me no help wasted today.

In Firefox, after a reboot, how can I re-open my previous sessions?

Originally I had quite a lot of open browsers & tabs. Then I needed to do a reboot, and now I've lost those previous sessions.

Usually I just open Firefox, and this opens one browser, and then all of my previous browser, and tabs reopen, but this time Firefox crashed, and its popup said it needed to restart, but it would re-open my previous browser and tabs, but it didn't.

After following the usual Firefox help guides, it still wouldn't re-open my previous sessions. Now if I ask it to open my previous sessions, it just opens the recent help guides, and not anything before the crash.

So is there a backup file of my missing sessions that I can roll back to?

I can't open Firefox browser. I get an error message, "Error: Platform version '127.0.1 is not compatible with minVersion > = 127.0 maxVersion < = 127.0"

I can only get Google Chrome.

Please advise

I am finding more and more sites that I regularly go to are no longer working on firefox. One site was because HTML5 apparently does not work on firefox. But others I don't know about why are no longer working on firefox. I thought it might be streaming related but just today I could not access one of my banks on firefox, and I tried many times, but had no problem signing on using Chrome.

Hello, I'm a web developer. I'm using the Firefox Developer Edition and currently working on a project that requires caret manipulation. I have this function right here that fetches the caret's client rect: ``` function getCaretRect(): DOMRect | null {

 const sel = window.getSelection()
 if (!sel || sel.rangeCount === 0) return null

 const range = sel.getRangeAt(0)
 const rects = range.getClientRects()
 if (rects.length === 0) return null

 return rects[0]

} ``` Here is where the issue arises. Suppose I have a contenteditable div with two line breaks (no new lines), and the second line is smaller than the first one. If the caret is positioned somewhere that is further than the end of the second line, and I press the down arrow key, then left, for some reason the caret rect I get has all values set to zero, like this: `{ x: 0, y: 0, width: 0, height: 0, top: 0, right: 0, bottom: 0, left: 0 }` I will add an image to explain further.

I don't have this issue on Chromium based browsers, but cross browser support is important for me.

There is one more issue to do with caret manipulation which is how contenteditable divs are handled. On a Chromium based browser, if I have a parent div that's contenteditable, then another div that's not contenteditable (contenteditable="false" explicitly), then two children divs which are both contenteditable (or more), I can navigate through the divs freely using the arrow keys and focus is managed better alongside event handlers. This is not present on Firefox, however.

If this is not the right place to ask for help then please guide me where is more suitable.

Im using Ubuntu 22.04 LTS Intel cpu I7 9th gen NVIDIA gpu but i disabled it My problem is that the Picture in Picture mode isnt sticky if i press anything it vanishes from view.

When I login to my main Firefox browser and then access a website within a short while the browser screen opens up again automatically. In other words, a second window which is very irritating. How can I stop this from happening?

gente, o que aconteceu com o firefox (normal, beta e nightly) que não funciona mais áudio. já tentei de tudo para reconfigurar, baseado em tutoriais na web, porém não se consegue mais ouvir áudio nos firefox.

As a longtime user of Firefox, I had a nice setup where after the start page, clicking on the Firefox icon would take me to a page headed "Firefox" in large letters. On that page I had placed the icons for my frequently used programs. Each of the small "icon boxes" had menus that would allow entering a URL so that when clicked, the desired app would open. I was exploring MS Bing, mostly because I like the pictures they put up each day. It looks as though a "new Improved" version of Bing brings along the new MS AI component. Together they seem to have removed my Firefox setup or hidden it where I can't retrieve it. By using Firefox settings, I was able to remove the Bing URL. Good riddance!, but can I retrieve my page of links to most-used programs? I don't know where to look for that. If I have to reconstruct it, how is that done. Or how can I start a replacement. Sincere thanks, Greg Schultz

Hi,

I need to take part in a course that is delivered via moodle and that employs SCORM videos.

After some modules I am experiencing an issue where firefox does not load them anymore. When you try to load a module a spinner appears and stays there indefintely.

Initially, trying to reload the module could eventually unblock it. Now this is not possible anymore. Disabling the enhanced protection does not change the situation.

The modules work just fine with chromium.

Having firefox being a stopper for online learning resources is a real issue. Any help will be appreciated.

Is there a way to set a separate theme for the private browsing option? I like being able to visually distinguish between the normal browser and the private one, but enabling a theme seems to set the same visuals for both.

If separate themes are not a thing, perhaps they could be added in a later update?

Thanks for all your time and effort.
