Firefox Support Forum

Typing the problem in the quote marks in the search box yields over 400 identical questions. So obviously this is a known problem with FF, and hopefully with Mozilla.

With me it happens on Facebook. Clicking "wait" basically does nothing, clicking "stop it" it basically stops the page from loading, so you can't post a message or have any interaction with the site whatsoever.

All along I'm watching the CPU at a constant 50%-60%, and memory for one tab of FB going up steadily from 400 MB to 1.2 GB (almost like a memory leak).

Now, my laptop has really limited specs, 3 GB RAM, Win 7, 10 years old. So I thought the laptop is probably to blame. Till I did the following experiment: Let's try Edge, with the exact same tabs, exact same sites.

So, one tab of the same FB page + one tab of Yahoo Mail -> FF: 60% of CPU, 1.5 GB of memory (and counting). Edge: 10%-15% of CPU, 500-600 MB of memory, and FB smooth as silk.

Any suggestions/solutions are welcome.

I installed an older ESR version on a used laptop I got a few weeks ago. Everything's working fine, except the following issue with Bookmarks:

On my Bookmarks Library page I keep two columns, Name and Added (because on some folders I have many bookmarks and I track them by the date added). When I move any bookmarks to another folder, the "added" date becomes the date and time I moved them(!). Also, when I change the bookmark "name", it also changes the "added" to the date I changed it(!). Basically Added is acting like Last Modified.

Any ideas what's going on? I've never had this issue before.

I have discovered a bug in the Sync. While starting a fresh copy of the browser and signing into the Sync, the content that was earlier saved to the Sync server is not fully restored.

As example, I use the "Preferences".

Some settings, like for example: "network prefernces", "search", etc., instead of beeing restored from the Sync server, are set to the default values and need to become changed manually into the prefered values.
