I already upgraded my home's internet speed up to 1Gb. It included a router's change. The fact i, when i do a speed test on Firefox, it does reach only 600 Mb download speed and 100 upload. If i do the same speed test with another browser, i get 900 MB download and 100 Mb upload. So , how do i configure Firefox in order to get same values than Edge and Chrome browsers? I understand it might has to be with some parameters in about:config . Could you give me some light on this? Thanks

It's on an older machine but updating my hardware is not an option right now. I don't have this problem on any of my newer machines. I've been using firefox exclusiverly on multiple machines for more than 15 years and I have never had this or any issues until now.

Formerly, one could reorder tabs in a Firefox browser window by clicking and dragging. One could also click and hold a tab and move it to create a new window or take a tab from one window, click and drag it to another window. I am no longer able to do this on my Mac laptop, after updating to Firefox 71. I can't seem to find a special setting in Firefox 71. Is there one or a way to allow tab movement? Or do I need to revert to the previous version of Firefox?

I'm scared af. Hundreds of password are saved on my firefox. My active logins were revoked and I had to reset the password to login to my firefox on windows. Turns out all my passwords are gone.

I have no email from firefox notifying of the suspicious login.

What I can do?

Hello!

I have firefox 74 (64-bit), after one of the bluescreens that sometimes happen for my laptop, my Firefox tabs became very, very transparent.

This is it how it looked before: https://puu.sh/Fnzh1/b606c91b73.jpg

This is how it looks now: https://puu.sh/FLYyk/63fb3fab0e.jpg

As you can see, in both cases I have 3 tabs opened and some other firefox window below. However, opacity is very high in the first case and you almost don't see anything else aside of the 3 tabs opened, while in the current situation is like non-existent and if not the difference in the size of the tabs, you wouldn't even notice that these tabs are not from the current window, but from some other window below!

Can someone help me understand how it happened and, more importantly, how to fix this problem? I tried searching options for things like 'transparency', 'transparent', 'opacity', etc., but couldn't find anything :-(

Running a speed test in Firefox will show lower download speeds, in some cases just a fraction of the speed of my broadband connection, both on Windows and Linux installations of Firefox Browser. Safe Mode makes no difference. Other browsers show normal speeds.

After my Firefox took a 'ninja update' I was not able to keep the cache clear and even though it was set to clear my cache on exit when i would open a fresh instance of firefox it would have items in the cache. nothing I would do would correct this even completely removing Firefox, the profiles, and reinstalling it. Reinstalling it is turning out to be my biggest mistake. Instead of the version 63 installing, which is what my installer was for the installer is only installing the most recent buggy version My version 63 had updates turned off, it should not have taken an update but it did even though the updates were turned off FOR security. I even had the registry set to block from HKLM When I am 'browsing' the internet I am logged into my machine with a user account that can't even make any changes. The current version (76.0.1) is having the same problems that plagued me before after this 'ninja update', the cache will not fully clear. When I open firefox it is showing it has items cached. There should be NOTHING in the cache when it opens, I do not have a home page set, there are no links set to open at startup and no connections should be made. The popup blocker is not only not blocking any popups it is opening them in new windows The machine does not have a virus or malware. Why is firefox so insecure now? The whole idea of using firefox was to be using a secure browser and just a browser it is not supposed to be integrated into the operating system it is not supposed to be interacting with the operating system it is supposed to be an internet browser. Without the ability to prevent this automatic communication and block unwanted traffic from it we may as well be using Internet Explorer, Edge or Chrome. How do we install one of the older more secure versions of Firefox without it automatically updating at the time of the install? How do we actually block the automatic communication? How do we block popups as the popup blocker does not work at all? (it worked beautifully in version 63) How do we get it to clear the cache at exit and open with the cache at 0?

I have bookmarks to multiple pages in the same domain and they show up with the same icon. How can I change them so that I can differentiate them? I prefer to just have icons instead of names/text for my bookmarks.

My Top Sites works well if there is a short name under the tile or I recognize the thumbnail. In other cases I see something like "Websu..." as the title. Hover over that and I should see a tooltip with the long name completed.

Is it possible for Firefox to put tooltips for when the name ends in "...?"

Is there another work-around I can use -- create a thumbnail that better identifies the site is one that comes to mind. Rename the site with a shorter name?

Thank you.

Whenever i use firefox i get spikes in my CPU usage, sometimes up to 100% usage. When i tab off of firefox, it soon goes down, then comes back whenever i have firefox active. I have tried restarting with add-ons disabled, creating a new profile, reinsalling firefox, disabling and re-enabling hardware acceleration, all to no avail.

Hello, Is there a way to make Firefox keep .part files when the download fails because of network error? My 3GB slow download just got interrupted in half and fully lost. Thanks.

I signed in to my Firefox account from my android device. It shows up in Devices and Apps, but when I click "Send tab to device" it says "No devices connected". I clicked "Connect another device" but it doesn't show up there either. Please help.

This just started after Windows 10 update KB4551762 installed. Firefox 75 still browses OK, but will not download any application installer files. Another Firefox-based browser (Palemoon) suddenly has the same problem. Non-Mozilla browsers (Opera/Chrome) continue to download application installers OK from the web. Tried refreshing and reinstalling Firefox 75, but that does not fix the problem. I suspect the Windows 10 update rather than Firefox, because the latest Firefox in a Linux system works OK.

I have had a number of unknown websites that I have had data breaches on and I have no idea of how to remove / protect / report these sites that are stealing my information? I can't change passwords on sites that I have never visited or registered at, so how do i remove and protect myself??

Extensions are installed and running but dont show up next to the 3-bar menu. Add-ons Manager says "The following extensions do not have shortcuts:

   Facebook Container
   LastPass: Free Password Manager
   TrafficLight"

They used to show up a couple of days ago but I cant find the area in Options to correct the problem. How do I make them re-appear?

Thank you in advance, Jerry
