When I open many new tabs, I'd like them all to be loaded immediately (as soon as they the new tab is created, a.k.a. eager loading). The reason is that, when I click to actually see those pages, if they are already fully loaded, that will make user experience much smoother.

Please see attached image for a demo of current behavior: browser had plenty of time to load those new tabs in background, but it didn't.

I understand that lazy page loading is a way to preserve RAM and CPU cycles. I know that is usually a good thing for users who are used to working with only one thing at a time and/or have limited hardware resources. However, I think there should be an opt-in feature of eager loading, which would optimize a lot the time for experienced/heavy users.

Thank you!

Hi how can I change my browser back to how it was before the update this morning? A page came up which said something about an update but I accidentally clicked off it and I'm not sure if I picked an option to change the buttons but now they're all circular and and it's hard to see what I'm selecting because of the colors and it's hard to read the names of the tabs now they're very short only the first word or part of it. How can I change it back please?

Thank you for your time,

Linda

For some reason, Firefox is all messed up . Happened suddenly. Some sites are blocked and says " ⚠ Firefox’s Enhanced Tracking Protection (Strict Mode) is known to cause issues on x.com"

But I'm not using Strict mode. Standard is set.

Or Malewarebytes will block the site and I have to click Continue.

Or in Yahoo.com, Yahoo is written in big black letters on top, and as I scroll down, there's nothing but empty boxes, all on a white background.

No, this is not happening on Chrome. All is normal.

What is going on?

Firefox created a folder "Old Firefox data" on my desktop which is impossible to delete. I am getting an error "Access denied" even when trying to delete it as administrator. How can I delete this folder?

Hello everyone.

Firefox updated today. I don't know—maybe some people like the new design of the tabs, the buttons in the drop-down menus, and the gradient borders around the active tab and the tab bar itself. But I’d like to revert to the old interface. How can I do that?

Thanks!

Hi,

Firefox was just upgraded to version 157 and there is now a large amount of wasted space above my tabs using the "Tree Style Tabs" plugin. Is there a way to get rid of this? (see attached image)

Also, is there a way to get rid of the rounded corners on the top left of the page because that just seems out of place... why is it there? the bottom and right of the page are not rounded. (again see attached image)

Also, now vertical tabs are a thing, is there finally a built in way to turn off the horizontal tabs, but without turning on the vertical tabs? I much prefer the tree structure of TreeStyleTabs (unless I have missed a tree in vertical tabs) but this leaves the horizontal tab bar which is again just wasted space.

My browser is using 2,3 Gb of extra ram it goes away by restarting but comes back in 5-10 min. It occurs wathing twich, i have tried disabling extentsions but it doesn't work. in about:memory the readout is as thoug it is keaping an extra copy of open browser files in ram.

Browser Guard - page blocked. Website blocked due to riskypattern these are tabs I have been using for weeks from trusted companies. But all tabs had this blockage. joe

After a recent update - I can no longer copy a title from an article and get the full URL to paste in OneNote.

For example with this article - If copied it and pasted it in OneNote it would appear this way

How to Link Notes in OneNote (2026) From <https://www.usecarly.com/blog/how-to-link-notes-in-onenote/>

But now I get this:

How to Link Notes in OneNote (2026) From <https://www.usecarly.com>

I made no changes to OneNote and in settings there: Include link to source when pasting from the Web is checked.

This function is working in Chrome as usual. But no longer in Firefox.

What setting can I change?

Thank you

First the laggy, extremely slow issue was just noticed on YouTube. Now I notice it on Rumble and other sites. For now, I have to abandon Firefox and use an alternative browser. I've stayed with you for years. Maybe it's time to part ways. I really like your browser. But, it has become nearly non-functional for me.

There's three images on the page, in FF only the top one shows, but if I hit refresh, all three show, but only for half a second, then they wink out. All three show in Chromium just fine.

Firefox just forced a terrible update on me that makes everything look round and different and I hate it so much. I don't understand why they think people want things to change all the time instead of being allowed to get familiar with something and now have it change on you without even asking if you want it to change!
