Firefox Community Forum

Original FF user here so not a newbie. Run all FF updates on a regular basis. Currently on a MacBk Air circa 2020 running Sonoma 14.7.7 I browse twitter on a regular basis. I run various ad blockers: ABP, Adblocker Ultimate & Privacy Badger. Last month or so I've needed to make some adjustments as maybe the X platform has instituted workarounds or something but suddenly I was seeing ads that looked like someone's post, very deceptive. At one point it was necessary to disable Privacy Badger on twitter/X as there was an interference w what I was seeing. That wasn't that long ago, maybe 2-3 wks? Consequently if I saw an ad I needed to do a "block element" thru Adblocker Ultimate & while it was a bit of a bother that was all fine and good no problem. Again, this was all recent. Tonite was different. An ad appeared and somewhere something got entangled and I had to disable the Adblocker Ultimate. I sent them an email to see what's up. Then I had to disable that on twitter so ads appeared. Next I tried to enable ABP again on twitter to see if maybe since I'd disabled it a couple of wks prior maybe it had been updated and would work ok. This is when things really started to go downhill. It worked but too well - was disabling images from news reports and/or someone's posted video. THEN I noticed my cpu was running a bit loud. I tried to disable/test the ad blockers but my cpu was getting louder so I shut down the twitter website altogether.

That didn't help. I checked the Utility monitor and saw my activity monitor climbing as I heard the fan running louder. SO bizarre! I shut down FF altogether and this calmed down the CPU. Next I opened just a general news site - Al Jazeera - to see what would happen. Within about 2-3 mins the CPU started speeding up again. I closed AlJazeera, and just sat there for a few moments and my cpu calmed down. Opened it again same thing. Began speeding up. That's when I came here to file a report//ask qs because this just doesn't ever happen - literally ever. It is not unusual for me to have both a browser page open w 2-3 windows along w a private window open - maybe mltiple windows there - and NO cpu noise going on. Once more I shut down FF completely before reopening a new window. IF I start browsing a news site - like Al Jazeera, it begins running hot again. Twitter, same thing and now my ad blockers seem to be messed up//not working as well. Right now as I type this I have ABP & AdBlocker Ultimate both highlighted as active; Privacy Badger is showing enabled but no activity, Twitter Video Downloader is just sitting there as is typical unless I need it (it's to download videos off of Twitter, works very well too.) That's all I have for add-ons. Right now in just this window everything is calm and quiet. IF I open a news site tho, or social media, anything w a bit of activity on it everything starts humming louder and louder. I just opened FB for a few moments to see if that creates issues and yes it does w/i maybe 2-3 mins of activity. Also: FF Privacy & Security Settings are on Standard. Not sure what else I can provide but please feel free to ask. I may have left something out. I'm hearing the cpu heat up again so getting ready to just shut things down for the night. Thanks to all who helped build FF - really - and thanks to whoever can help resolve whatever's going on now.

In my Settings, the browser's fallback language is set to Portuguese, without giving me any other language choice, nor leaving it blank. I assume this is the reason I keep seeing menus, notifications, etc., randomly popping up in Portuguese.

Hi guys - I am running Firefox 157.0 (aarch64) on a Macmini M2 pro with 32GB RAM .

I am regularly receiving messages that my default browser, Firefox, is the largest consumer of that RAM. This is what I received this morning shortly before my system shut itself down. I did have many files open but noticed that Firefox is consuming 33GB of my RAM. Is this normal?

This morning, I can no longer download (Save) files to my computer, nor check/change settings in Firefox. Tried all troubleshooting steps to no avail.

If I delete and reinstall Firefox, will I lose all my Bookmarks, etc.? Running version 157.0 (aarch64).

Appreciate any help!

I used lightspeed POS program. We have specialized forms that print out for us created by a third-party developer working with light speed. A few months back you updated Firefox and it changed our printing where the forms do not print exactly like before. Can this be fixed by you?

I'm trying to transfer bookmarks from Chrome but when the window opens Chrome is not an option, only Safara and transfering html and cvs. How do I access Chrome? I'm on an iMac. Thank you.

Dear M, the toolbar themes are worse than glass, in readability

How do I change the color of bar and tabs, so I can spot the active tab without ruining my eyes and mood? (The only themes in 157 that are not from a child's dream are still useless, because the tabs have nearly the same color as the bar, and, as you pointed out, lack the previous visual accents like shadow or line.) I understand there is a very good reason to remove the old themes, but please explain how to change these two tings:

- tab bar and tabs brightness - bar colors or brightness (lower bar with address/search field and bookmarks bar)

Or better still, put back the theme I chose that gives me a dark mode fitting in with Mac apps. (Since I don't know if there is a backup, I cannot even figure out the values of old themes.)

Thank you

All of a sudden all of the videos I watch on YouTube with Firefox are defaulting to mute on my Macbook. I haven't made any changes to settings, etc. I don't have a YouTube account so I can't make any changes there anyway. I am having to unmute each video before I watch it.

I'm using Mac Catalina OS, version 10.15.8, and the latest version of Firefox as my browser. How can I increase the font and icon size on the Firefox toolbar?The existing font size is too small and hard to read. Going to about:config and clicking on "accept the risk and continue" plus typing "layout.css.devPixelsPerPx" doesn't seem to work for me. 'Simply put, I need clear instructions that allow me to resolve the aforementioned problem.

I am trying to watch you tube TV outside of United States. I am unable to connect to You Tube TV because it says that it detects a VPN proxy. How can I fix this so I can watch You Tube TV

The edit icon on lower right splash page selects which photo for background display. My photo will not display and ignores my selection. Nothing happens. I have spent 24 hours trying to customize my Firefox but cannot complete my goal. Help!

The new Firefox (157.0) is not allowing Amazon Music to play in the web version. Worked fine before. I turned off Ad blocker and it still is not working. Amazon Music has to allow a window at the bottom of the page to show song playing and whatnot. Please help!

After Firefox upgraded to the latest version, Google no longer opens up, bookmarked websites no longer have my username, password, or login account info, and do not recognize my account. Syncing caused all kinds of problems. I'm not happy with Firefox anymore and wish to remove it from my laptop . How do I do this? Sorry...I was once a happy camper. Barbara
