Is it possible to view the contents of two tabs simultaneously? I have been in many situations where it would be very helpful to view two different web pages side-by-side to more easily make comparisons. Opening a new window and viewing them side-by-side is similar but being able to pick two tabs to view in one browser would be a lot faster and easier to control.

Hello support team,

I would like to inform you that since the last update in firefox 140.0.2 (64-bit) the pages of Proton mail do not load properly.

Logging page is successful Logging in is successful

Starting page isn't loading and redirects to error message. Reloading the page doesn't help.

Thank you for your consideration.

Best regards,

Currently I only have 3 tab groups (private, tabs, sync) available in the iPhone version of Firefox. Are there plans to create tab groups like safari? If they already exist, how do I create a new group?

Yesterday, I had Firefox open and running perfectly fine, and I had forgotten to shut down my laptop before closing it. Today, when I reopened my laptop, the Firefox window that was open instantly closed. I tried opening Firefox again, but it kept opening and closing immediately. It would show that there was an open window of it, but the window itself wouldn't open. It would run in the background but never actually open. I tried uninstalling and reinstalling, but it still did the same thing. Does anyone know a solution to this?

I took a look today and I had 237 MB in cookies! This was after clearing the cache of all files. I've only had this (new) machine a couple months.

Short version: Sites have "cookies" from 200kb to as much as 34MB! For many of the sites over 3MB I have no account and have visited them only briefly.

To be clear, I don't care about the space being used. It's trivial. But what the heck is FFox storing and calling it "cookies"? Last I checked, a site was still limited to 4K size cookies and perhaps 50 per domain. So how are we getting to MB+ sized "cookies" per site? Again, the cache was cleared, so what's left aside from trivial cookie files of <4KB?

Hallo Mein Name ist NIco Büchner.

Ich habe in der letzten Zeit öffters in meiner chronik seiten wie bcclk.com und andere Seiten, welche ich nie geöffnet habe gesehen. Das macht mir etwas angst. Auf dem Foto sehen sie einen Auschnitt meiner Chronik. Ich habe von den Seiten die sie da sehen keine jemals gesucht auch nicht die für E bikes etc. Ich wollte wissen ob diese Seiten schädlich sind oder Sicher. Wenn sie nicht sicher sind wüsste ich gerne wie ich sie entfernen kann.

Danke für ihre Hilfe.
