Firefox Community Forum

Hi all the people,

I was just surprised to see this in an Apache HTTP log: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Firefox/58.0.1"

This bugs me. My first guess would be that a Webkit based Firefox could not be qualified as really Firefox. Although that, I could imagine a Firefox for iOS or MacOS based on Webkit, may be, but it says it is on Windows, which makes less sense.

I suspect this is a user agent string spoofing, but I just need to be sure (I try to get ride of far too invasive bots, while I’m afraid to disrupt browsing from legitimate web users).

With thanks and my apologizes for such a question which may looks obvious or strange to people who know for sure.

macOS Tahoe; 26.4.1 Firefox 150.0.1

I keep most of my bookmarks under the "Bookmarks Toolbar"; I have quite a few of them.

I've always enjoyed the ease and utility of the "Add Folder..." menu item in "Manage Bookmarks", but now it fails on each and every attempt to add a new folder! For example, if I select a folder under "Bookmarks Toolbar", right click that folder, and select the "Add new folder..." item from the drop-down menu Firefox simply "freezes up" - becomes totally non-responsive (spinning beach ball!).

The only way I've been able to recover is using the macOS "Activity Monitor" to "Force Quit" Firefox! If I repeat the "Add Folder..." process described above - Firefox "freezes up" again. I've tried re-booting, and that doesn't cure the problem.

Without trying to confuse the primary issue, I have noticed other "bad behavior" from Firefox:

1. 1. Firefox "disappears" from the menu bar regularly. I can get it back by moving to another desktop, and returning to the desktop with my Firefox windows. However, it will disappear again in short order.

1. 2. Firefox is very slow loading some of the web pages I visit regularly.

When did this start? It started very recently. I have a new (about two weeks old) MacBook Pro. The "Add Bookmark.." issue began only today, but the other issues I mentioned have been around longer.

This is frustrating... I suspect this is caused by Apple's macOS software, but of course have no way to prove that! And in the "FWIW Column": my Chrome browser has basically the same function and interface for adding folders, and it still functions flawlessly.

Hi. Now that the 'Open Link in Split View' has annoyingly replaced the spot previously held by 'Open Link in New Window' i keep clicking on it accidentally (muscle memory).

I don't want to have to retrain my muscle memory, but despite creating css file generated by Claude that should in theory remove the option, and putting it the Profile Folder, it will not go away.

How do i remove it?

Nach dem letzten Update auf Version 150.0 wurde ich auf den integrierten VPN-Support hingewiesen. Eine Aktivierung ist nicht nöglich, da ich die Aufforderung zur Aktivierung nicht finde. Gehöre ich noch nicht zu denAuserwählten oder verstehe ich etwas falsch?

Auto updated to firefox 150 yesterday. What's new screen announced the rollout of the free in browser vpn had reached us (in Canada). Clicked the link to set up, went to screen to follow instructions. There's no vpn icon in the firefox menu bar, no matter what I do. (And I have done everything obvious.) Was the VPN not in the actual update I received or is this some bug/glitch? Thanks.

I want to setup the VPN in firefox but the instructions refer to the VPN icon which is not visible to me. When I try to add it to the toolbar the instructions say to click more tools from the menu at the top right, but there isn't a selection called more tools.

Unable to upload any images to Gemini. Working fine on all other browsers. Images always fail unless security levels set at lowest. When the do upload the action button does not become active

I've recently switched to Firefox but am finding some of the performance a bit cumbersome. I am continually being asked to hit "Send" ["To display this page, Firefox must send information ..."] when I am logging into my Outlook email or looking at my bank information. I'd rather not be "resending" these pages each time and am wondering if there is a setting.

Hello all,

I am currently testing the new VPN feature in Firefox. I Is noticed that Firefox always starts with this integrated VPN being off. I searched but I didn't find any way to have it always on when launching VPN. Is that possible?

Thanks!

When I try to use multiple desktops to arrange the opened windows, the window of Firefox is present in all of them, even the last one, which is usually totally empty (and when we drag a new window in it, a new empty desktop is created).

You can find attached screenshots of my three desktops, where Firefox appears (I blurred all info that could be sensitive, I hope I did not miss any !).

Is there a setting to unset this ?

NB: this is a duplicate of a post I made on askUbuntu, but it seems that this issue is more Firefox related than Ubuntu... And I did not manage to fix it with the answer provided there, so I'm trying my luck here !

NB2: oops, i just noticed that I inserted this question in the wrong topic (android), it seems that I cannot change that... I anyone see how to do it let me know !

Due to muscle menu or not needing to think about it. Split should either be near the bottom of the context menu or you should be able to toggle it in settings. The amount of times I have gone to click a link to open in a new window only to split the view is driving me crazy.
