I can no longer pin extensions/add-ons to the toolbar. My interface does not look like the one in the help section. I don't see a gear, I see three dots. And when I click on the three dots I don't have the option to pin to toolbar.

I am using Firefox 147.0.4 on Mac OS 26.3 Tahoe.

So i was going to go to the forums to whine about the new phone layout (cause it's ugly, less compact and laggy to the point of freezing) but the forums seem to be down rights now.

I'm trying to find a solution for having all tabs open across devices. Currently, my desktop has about 50 open tabs that I access regularly. Today, I installed Firefox on my laptop, signed in and initiated syncing. All bookmarks came over, everything looks great, except that none of my open tabs from the desktop browser show on my laptop.

I would like to have identical tabs open across devices. Is there a way to configure this where a new computer being logged in automatically receives all open tabs from the initial device and then tabs automatically sync based on whatever is opened/closed on either device after the initial tabs are identically synced?

I just got a new Dell Windows 11 desktop PC to replace my old Dell Windows 10 PC. Since switching, there are three sites that will absolutely not load the homepage: Paypal, Venmo, and Common Dreams (which is a news site). The same sites continue to load instantly on my old Windows 10 PC in Firefox, and on the new Windows 11 PC on Edge. Firefox is the only browser I use, I just use Edge to test sites, I uninstalled Chrome because of Google's privacy and AI issues.

In the lower left corner of the window for these three sites are the following messages, for the three respective sites:

• Waiting for www.paypalobjects.com...

• Sending request to jssdks.mparticle.com...

• Waiting for www.commondreams.org...

What's going on here? Seems strange that Firefox continues to behave normally on Windows 11 for all sites except these three, and works perfectly for these three sites on my Windows 10 PC. How can I further troubleshoot and fix this? I don't want to have to use Edge to visit these three sites, esp. Paypal and Venmo.

I'm guessing it has something to do with cache or history but am not sure how to proceed...

I purchased Mozilla VPN (new customer) on February 7th. I canceled my VPN subscription yesterday (February 17th). When I signed up I was told that I have a 30 day grace period to get my money back. How do I get my money back?

In a thread discussion about the flag, "browser.tabs.unloadOnLowMemory" dated 23-Nov-2022 (https://news.ycombinator.com/item?id=33706117) it was mentioned that we've disabled tab unloading on Linux because low-memory detection just didn't work.

Has the issue been fixed? Does the low-memory detection work in Linux? Can it be enabled now?

Does it get triggered when SWAP is being used? Or when system free RAM falls say to about 25% of total physical RAM?

I have at least one question on the support forum which has never been answered. So I went to Bugzilla, and discovered dozens of YouTube issues under the Open/Unconfirmed status.

I can reproduce my problems. I'm sure others can reproduce their problems. Nothing is done. NOT EVEN admitting there is a problem.

If I can't use YouTube on Firefox (I can't), then why am I using FF? It is one of the biggest sites on all of the internet. But FF apparently doesn't care if it doesn't work.

What. Is. Going. On?

I am switching from firefox to firefox-esr. Version 147.0.3 to 140.7.0esr, start firefox with --allow-downgrade which mostly works. What does not is the "Home default" page, it is blank and can not even be configured to what it was because the settings page is also blank, nothing below "choose what content ...".

I have done this on 4 machines now with same failure for the home page. settings. My previous workaround was new profile and import data so the setting page is therein ESR. This is a far harder than it should be there being no single export-import. I had to export import history with a third party plugin and cookies the only method [I found] was to copy the sqlite file. Others like password export-import are fragmented.

I cannot find how to add a New Bookmark to an existing bookmark folder from the screen when I am visiting a Website I wish to Bookmark. Should be simple, but I cannot find out how to do it. There is no simple drop down menu that says ADD BOOKMARK and give you a choice of what folder to save it in. HELP !!!!!!!!
