Firefox Community Forum

Hi. While clearing my browser history the other night some of my bookmarks also got deleted. I understand once browser history is deleted it cannot be recovered, but is there any way a deleted bookmark can be recovered?

I am trying to set up a vpn using Proton as a Firefox add-in but Firefox won't let me use it, saying it has invalid credentials. I can't contact Proton because if I enable it as an add-in to Firefox, I can't use my browser. Do you know of any other vpn networks that work securely with Firefox?

I want to use the new search bar, but my Firefox browser shows the old address and search bars. I have been upgraded to Firefox 140.0. I am using Windows 11 on a desktop. How do I make the change? Thank you.

I wasn't sure what to select for the type of question so you can move it if you think another type would be better. I would have selected crashes but that isn't an option.

It happened again a few minutes ago while watching Star Trek First Contact. The Phoenix was about to go to warp and Firefox CTD with no crash reporter and when I looked in about:crashes there was no crash report. This exact situation happened twice while watching the movie Signal unknown or whatever the title is.

All of the sudden Firefox no longer opening previous windows and tabs on startup, which is how I have had it set up forever.

The last few days, instead of opening previous windows and tabs when I launch FF, it opens mu Home Page. I then have to "reopen previously-closed windows " or "restore previous session."

Regardless of which I choose, I then have to manually close the first FF instance (the one with the single tab - my home page). Then when I'm done with my browser and I X out of it (or Exit" out), when I come back in the same thing happens - I'm presented with my home page, not my open tabs.

I'm having huge memory problems with Firefox. In about:performance I can see that the extensions process takes up way too much memory. When I start Firefox it usually shows a memory usage of around 180MB. However, at some point the memory usage of the extensions process starts to increase and it doesn't stop increasing until my RAM is full and then it increases even further. It increases until I restart Firefox or until it uses so much RAM that my computer runs incredibly slow.

Below you can see a screenshot of the Task Manager showing how much RAM is available on my computer and a screenshot of the about:performance page showing the memory usage of the Extensions process. The RAM available on my laptop is 10GB (the default configuration was 4GB of soldered RAM plus 4GB of exchangeable RAM. I have upgraded from 4+4GB to 4+8GB but 2GB of the soldered RAM on this laptop are used as GPU memory so the remaining RAM is 10GB). The about:performance screenshot shows a memory usage of 13GB for the extensions process which is possible because Windows automatically pages RAM on the SSD when I'm running low on available physical memory. This enables programs to actually use more memory than the available physical RAM but of course programs become incredibly slow when the RAM is full and huge parts of memory have to be paged on the SSD.

My actual question: How can I find the cause of these memory problems?

What I've tried so far

- I have created a memory report on about:memory. The result is at the bottom of this post. - I have watched the about:performance page and tried to find out what action triggers the memory usage of the extensions process to increase. At the start of the browsing session the memory usage is only at around 180MB. It stays like that for a while. At some point it starts to steadily increase by many GBs. But I couldn't find the cause. I don't know what triggers the extensions process to increase memory usage. - I could simply disable extensions and see if the problem gets solved. But I want to know which exact extension causes this problem. It is very difficult to find out which one it is because I have many extensions and I don't know what causes the memory usage to increase. So I would have to disable extensions one by one and wait for an indefinite amount of time and check whether memory usage stays low. But I don't know how long I have to wait until the memory usage would increase because I couldn't identify what triggers it to increase.

Rather than just using trial and error I would like to find a way to use debugging tools to exactly determine what causes the problem.

This (https://pastebin.com/U3QXTAt9) is the memory report from about:memory. This contains the whole extension (pid 18332) section (copy & pasted by selecting the text on the about:memory page). I have left out the rest because I don't know if it contains private data. Please note: this is not taken from the same browsing session as the screenshot that shows a memory usage of 13GB. Why? Because programs run very slow when memory is low and large parts of memory are being paged. The debug tools usually require a lot of RAM and CPU performance so it's very difficult to use the debug tools when the memory is already full and programs are already running slow. This memory report shows a very high memory usage of the extensions process. In this case it's "only" 3.5GB but it was taken in an early stage of the increasing memory usage. As shown in the screenshot below, memory usage can go even higher than the available physical RAM on my computer. The memory report doesn't clearly show which extension is responsible for the high memory usage. In the memory report, I can only see a high memory usage for the items gc-buffers and gc-heap which leads me to think that the memory problem has something to do with the garbage collector. However, I cannot see which extension is responsible for this. No item in this list with a description that identifies a specific extension has a high memory usage. This is only an excerpt from the memory report (only the extension section). I went through the whole memory report with Ctrl + F "moz-extension" and looked for items with a high memory usage but I didn't find a single item with high memory usage that belongs to a specific extension.

After manually deleting a link from my bookmarks, that unneeded link is still suggested in the address bar after the fact.

This is while using the Windows version of Firefox 140. In the Search > Address Bar — Firefox Suggest section of settings, I only have the Bookmarks option enabled. I've tried disabling History > Remember search and form history and enabling History > Clear history when Firefox closes options as well but still have the problem.

I'd really appreciate any advice.

On a brand new powerful PC just signed in and there's no Add ons showing on this device.

I have two other devices where i have no issues, but this one...

What can i do?

This what I get many times a week. Can you put a command in your software that I don't give damn load it anyway!

Help me find an extension that will allow me to email a link to a browser page through Outlook email directly from the browser page. I had one on my old computer in the Firefox extensions bar, but I can't seem to find it again. When I search there are many that either a) don't work, or b) may not be trustworthy. Help!

When I try to sign in to Yahoo I am sent to a Google sign in. I tried that and only got gmail and not my yahoo mail. I can sign in fine when I use Firefox private browsing and Edge. Why is Google involved with Yahoo mail?
