When a link from outside Firefox opens the desktop browser, it displays the default home page but does not continue on to the URL specified in the link. This is new for me in V 152.0.6 (aarch64) . Mac OS 26.5.2 (25F84)

When checking out the new features the ' Learn More' link under Tab Groups directs to the article explaining Pinned Tabs, there is no way to get to the explanation about Tab Groups

Hello community,

I've been moved to MacOS at work and since then, Firefox will not always restore my pinned sites when I start it the next day.

Here is what I do:

1. Right click a tab, select "Pin Tab"
2. Go about my day
3. At the end of the day, I close Firefox by using command Q and shutdown my Mac
4. The next day, I start Firefox and most of the time, my pins are gone

I did not have this issue on Windows Firefox. I am using MacOS 26.5.2 and Firefox 152.0.4 Firefox says "Your browser is being managed by your organization" in settings. It is a link that can be clicked and the only active policy showing there is "DisableAppUpdate" which I assume is because we have our own tool to manage software updates.

Any idea what could cause my pinned tabs to disappear? I did not really customize the settings so far, I do NOT clear browsing data when exiting FF and the startup option "Open previous windows and tabs" is NOT selected. I have Ecosia and 1Password as plugins.

Any help appreciated, thank you.

Hello there,

I’m experiencing high memory and CPU usage in Firefox, which is affecting my computer’s performance. One issue appears to be that “FirefoxCP Isolated Web Content” continues running even when tabs are inactive, contributing to increased resource usage.

Other browsers, such as Microsoft Edge, reduce memory and energy consumption by putting inactive tabs into sleep mode after a period of inactivity. I would prefer to continue using Firefox as my default browser, but I need a way to manage this level of resource usage.

Could you please advise whether Firefox offers a comparable setting, workaround, or planned improvement to reduce CPU and memory usage from inactive tabs?

Thanks for your help!

I recently made the switch to Firefox full time a few weeks ago, and in that time, I have been getting more and more annoying at how Firefox renders Youtube.com.

If I'm on my feed, and I click to watch a video, watch it and go back, I never know what I'm going to see when it goes back a page. Obviously it goes back to youtube.com, but I never know if it's going to load at the top of my feed, or about ten rows down. Even if I click a video in the very first row, and then go back a page, it may or may not load at the top of my feed. I could also actually click a video on the tenth row, and then when I go back, it might load at the top of my feed, though that is not as common, it has happened. It also sort of, kind of, reloads the page when it goes back, but never goes back to the point on my feed at the spot where the video I just watched is, as Chrome and Brave do.

This is not how Chrome or Brave do things, and yes, I know they use a different engine, and I'm sure that's the reason for this issue. Chrome or Brave, if I'm watching a video and click back to my feed, they are much better at loading what is in cache, even if I the video was on the 100th row. I can then manually refresh if I want to.

Or to open the profile selection sidebar?

I don't see it in about:keyboard but maybe there's something else somewhere.

If not, what's the quickest and easiest way to switch profiles?

Firefox drop down history shows about 85% favicon substitution for gmail entries. It is not the gmail favicon, it is a food blog I do not login to and only very occasionally read. It is a very random substitution.

Clearing cache, cookies and restarting did not eliminate the issue. All apps and browsers are fully up to date.

I only use Firefox so do not know if it happens on others. Also, it does not happen all the time, only about 85% of the time, sometimes within one session, as visible in the attached screenshot. The bottom 9 are gmail's and you can see it has chosen to substitute the gmail favicon for an unrelated food blog favicon, but the there are several gmail entries that display the correct google favicon.

It isn't a problem but it does make me feel less secure as it is a weird glitch. If there is crossover there, where else may there be identification failures? Is there any way to correct this? Thank you.

Firefox completely changed overnight without notice and I have lost all my bookmarks and can't find out how to access TV channels that were easily available previously on my desktop. Trying to make sense of changes but struggling. Nothing that used to work for me is still available. I don't even recognise it. Might have to give up Firefox.

Why I can select a custom page for when a new window opens but NOT when I open a new tab? I am tired of using your search bar because it is defaulting to the country I am in rather than only giving me results using Google USA. This is causing the results to be in a language I am not interested in using. I do not want results using the local Google, I ONLY want results from Google USA regardless of where I am at in the world. Please allow us to select a custom url for the search bar as well as a set url for every time we open a tab (not just a window).

This is a recent problem but when I try to open new tabs they don't load or take a very long time to load. I wind up shutting down my computer and resarting but sometimes that doesn't help. it seems to be getting worse. I do not use any other VPN but yours and Duckduckgo to search. I use a macbook air. Any suggestions? Thanks

I see many complaints about this new version v 149 for the Mac. The most outrageous one is that you can no longer drag links from a browser page (try BBC) to an email or a doc. You have to copy the link then it won't turn blue and only when received will it show up as a link. Like many others after 30 years use preferred over Safari and others I am seriously losing patience with Firefox. On the very day you announce split screen for Ff windows - you disable a vital feature that has worked for years causing me to waste so far 60 minutes of my hard pressed work time. Maybe this will be corrected in the next upgrade. But I am now intending to avoid all Firefox upgrades for 6 months after being offered. I doubt anyone on this forum will come back on this but my set-up is Mac OS Monterey - and Firefox v 148 worked perfectly before today. I hesitate to try and install the previous version because I am not used to doing such tech moves. Perhaps someone in the Mozilla head office congratulating themselves on the marvellous new upgrade will come across this but I doubt it

Hello, In FF 152.0.5 (aarch64) on macOS 26.5.2, I am noticing that every website that has a checkbox in a form does not work the way it should. The only indication that the box is checked is a slight "highlight" around the edge of the box, nothing actually in the box. See attached screenshot from the USPS website.

Also, the NO checkbox wasn't even visible until I clicked the area next to it. It was just blank.

I've seen this for set-up pages for WordPress plugins and on standard contact forms (using CF7 plugin) where the checkboxes so very little or no interaction to the user at all.

Grant it, I know now what to look for and how to use these. But any standard user is going to be absolutely confused by this unintended (I Hope) browser behavior.
