Gentlemen, isn't your browser using a lot of RAM? I've been freaking out about it in recent years. That's only with 25 tabs open!! Despite the fact that the system was installed just a day ago, without any tweaks!!!

Hello,

Since a recent update, I can no longer drag and drop files from the Firefox downloads panel directly into Outlook Web (webmail) as an email attachment. This used to work fine before.

Steps to reproduce: 1. Download a file (e.g. a PDF) 2. Open the downloads panel (the arrow icon in the toolbar) 3. Try to drag the file from the panel into the attachment area of a new email in Outlook Web 4. The file does not get attached — nothing happens

Expected behavior: the file should be attached to the email, as it was before.

Workaround: I have to open the downloads folder via the folder icon in the panel, then drag from Windows Explorer instead.

Firefox version: 150.0.2 (64-bit) OS: Windows Webmail: Outlook Web (outlook.office.com or outlook.com)

This is a regression, it worked in previous versions. Is there a fix planned?

Thank you.

i tried firefox, zen and librewolf but every of them has the same problem. smooth scrolling is sometimes good but sometimes so slow and laggy, especially in a tab that has a video. in tabs that has a video always have that issue and tabs that not has a video does it sometimes. its like scrolling is in 60hz when it happens. i tried uninstalling lots of times but didnt fix.

I am disgusted. I have been trying to sign in and first changed my password, but it still wont let me sign in and says my new password is incorrect. I've wasted almost an hour doing what should be fairly straightforward.

I've done recent updates (May 2026) and after having 3 updates in recent months, I still have difficulties with my video programs (both Zoom and "One-click) slowing down during my work which is 100% virtual. How can I revert to an earlier version where this was resolved, please!!??

VPN has appeared at the top of the screen with an option to click the GET STARTED button to try the built in option. I haven't done so but now can't access a website I regularly use. Their tech team tell me that the VPN is blocking access. How do I disable this when I haven't asked for it so don't know where to find it

I noticed there is a VPN button underneath the Firefox browser.

Is it already functional or, do I have to get it started?

Is it free or else?

Thank you!

Hello

I have just downloaded Mozilla to my new laptop. I have Mozilla on my old laptop.  Can all my bookmarks be synchronized with the download to my new laptop.  

Thanks.

why did you destroy the existing bookmark structure and replace it with something that makes no sense. I have no idea from where you obtained the url's for the stuff that's in bookmark's now. I also do not look forward to having to re-create all of the bookmarks I had in place. I won't be doing that on Mozilla! R Crider

I lost all my data after installation of new firefox. I have lots of important data in that profile.

I forgot the password to sign in and when I reset, a new profile was created for me and all my data are gone.

Now, I even know the original password. I did not know, I will lose my data. How can I get my data back? Please help.

Using the Firefox browser, I tried to copy an image and wasn't able to do so. Then I copied an image using another browser and wasn't able to paste it into a Facebook post on Firefox. Please tell me how to fix this. I can't copy/paste text either. Could the problem be my Mozilla VPN?

Ever since the last update of the Firefox program, I am frequently getting the "Server Not Found" message when I click on links online. If I switch browsers, the links work just fine so it is obviously Mozilla's problem and not anything with my "modem or router" as I am told int he "what can you do about it" message on this error. Mozilla needs to look into this problem and update whatever is causing the failure to link message.
