Firefox Support Forum

I am using the latest version of Firefox with Mojave on a Mac.

Lately I have experienced slowness despite the fact that I didn't add any software and I have Norton checking for viruses. Recently I got a message "Your system has run out of application memory" when I had 5 tabs open in Firefox. I checked Activity Monitor and it showed Firefox using 1.16 GB. 7 other apps were open, the next one with the highest memory usage was Mail (465 MB). Activity Monitor showed 30 instances of FirefoxCP Isolated Web Content entries.

I attached a screen capture showing what Firefox was using in one of these instances. Is this "normal" with 5 tabs open?

I closed the open tabs and quit Firefox. Memory usage by Firefox went down, but after a short time the problem happened again.

A search on the internet showed lots of similar complaints about FirefoxCP Isolated Web Content. Is this a known bug? Any way to avoid this problem?

Thanks.

This is my second posting of a question. See below. Also I don't know where to find the answer. Please send link or answer to hollandhouse@woh.rr.com. Thanks JHolland

I have a problem with Firefox 107.0.1 that needs your expertise. I’ve used Firefox since version 12 with no problems.

My Macbook Pro (on Catalina 10.15.7) is running Spectrum’s (Charter) Security suite and requires installing a spectrum extension in each browser. The extension installs on Safari (my backup browser), but won’t install in Firefox. Spectrum app takes Firefox to the web site to download extension, but nothing happens. Site can’t install the extension. The link is below. What’s the fix? Thanks John Holland hollandhouse@woh.rr.com

Greetings. I waited a long time before updating from FF 88 to FF 104, concerned that the header and footer issues I previously experienced (and resolved) with FF's print preview interface would recur after updating to a newer FF version. Unfortunately after updating to FF 104 the very same issues recurred. The only solution was to disable FF's print preview interface once again and use the Mac print window instead for all printing tasks. Doing that solved the issue with headers and footers getting cut off pdfs and printed pages, but it did not solve two new issues that began after updating to FF 104, which have persisted through FF 107.

When printing emails and/or content from webpages, FF has been inserting what I believe is called square box symptom (multiple square boxes in a row with question marks in some of them) instead of the actual text that is on the email or webpage. FF is also printing a long series of dots across the page in certain areas of my emails, which I assume are the very bottom of the letters that are supposed to be there. These issues have never occurred in all my years as a Firefox user until updating to 104.

Does anyone else have these problems when printing emails and/or webpages? This behavior does not occur with every email or webpage that I print or save as a pdf, but it is prevalent enough that I am having to rely on Safari to create pdfs and/or printouts.

I've done everything I can think of to resolve these two new issues but the behaviors persist. I am attaching 2 screenshots of a recent order confirmation email that I saved as a pdf to demonstrate what the issues look like. The title of the email is cut off. All you can see is a bunch of tiny dots. The amount of the refund is nothing but dots. The title of each item in the order is a bunch of dots, as is the price on the far right. There is a row of square box symptom between some of the items in the order, followed by more missing titles and prices represented by dots, and more dots for the amount of the discount and subtotal.

I was going to submit a bug about this but wanted to inquire here first in case there is a solution that I have not tried. Clearing cookies, cache, and running Disk Utility has not resolved this. Any assistance you can give me is greatly appreciated. Thank you.

had computer shutdown for a few days come back and lst time w/this issue; firefox will not load my yahoo page as usual, i get the error message above w/'try again'...not working. checked the 'lock' in search bar but can't follow the article's instructions. is there a quick fix for this i hope? thank you.

Hello:

This option used to work for me and then 3 weeks ago it stopped. It is very frustrating. My CC number is saved in the browser's settings and yet everytime I click on a place to autofill my cc info it shows up for a brief second and then DOESN'T autofill. What gives?

I took a screenshot of my settings.

I use layout.frame_rate 1 to block animation, and to replace painful partial scrolling with clean jumps. I can't use an intermediate frame rate, such as 3-30 fps, due to the seizure risks, or a high frame rate, such as 60 fps, due to migraines when hit by "smooth" animation, "ease in-out" animation, zooming animation, parallax animation, partial scrolling with one part of the window sliding alongside another, etc.

about:config involves some other frame-rate and frame_rate settings;

gfx.display.frame-rate-divisor starts at 1

layers.offmainthreadcomposition.frame-rate starts at -1

layout.expose_high_rate_mode_from_refreshdriver starts at true

layout.frame_rate starts at 0, which defaults to monitor settings; I've reset it to 1 (1 frame per second).

layout.throttled_frame_rate starts at 1

What are these and what do they do? I've tried looking them up, and see a bunch of posts about browser diagnostics, or *increasing* frame rates, or the like.

Summary: Having difficulties with "recently closed tabs" and some tabs in restore previous session.

Basic setup: Firefox 106.0.2 on macOS Mojave 10.14.6. Probably existed on Firefox 105.?.? though unsure of extent as in the middle of upgrading entire system. Private browsing has not been used at any point.

Problem 1: some tabs do not appear in "recently closed tabs". They do appear in normal history. Other tabs appear as hoped and restore normally.

Problem 2: some tabs do not restore when the session is restored. Again, these do appear in normal history. Other tabs appear as hoped and restore normally.

Problem 3: sometimes the tabs which had been restoring nicely stop doing so, and sometimes the tabs which were not restoring nicely do.

Problem 4: intermittent, tabs seem to appear in "recently closed" and seem to restore, but to old pages which had long since been navigated away from. Annoyingly, when these appear in the "recently closed tabs" they are listed with the hoped for title and favicon (for example, about three days ago I navigated to an article from ExampleForum.org, then used the back button to return to ExampleForum.org and continued to navigate around ExampleForum.org, but if I close the ExampleForum.org tab and try to restore, it reverts to the article tab despite appearing in the list of recently closed tabs as an ExampleForum.org tab).

Unable to figure out what is different about the tabs which do not restore as hoped compared to the tabs which do, and am having considerable trouble performing sufficiently methodical tests. I guess I have as many cognitive glitches as my current browser settings!

Things I have tried, in approximate order, several repeated having tried different things: repopulating tabs with the desired content then closing them, repopulating a new window with desired tabs then closing it, adjusting preferences in about:preferences and about:config, clearing the startup cache, solutions suggested here https://support.mozilla.org/en-US/questions/1202514 and here https://support.mozilla.org/en-US/questions/1197599, plus attempt to revert same, updating Firefox, rolling Firefox and the profile back to a previous version from a backup, resetting all containers, disabling multicontainer extension, opening tabs in new windows, consolidating windows, opening all tabs in one container, scrubbing older history, scrubbing all history, more combing over my settings, disabling syncing (this isn't set up with a separate device yet).

Things I have yet to try: disabling all containers, using a fresh profile, disabling all extensions.

Further details part 1: when the sessions are restored, new tabs appear in lieu of the pages I want. These are in the containers assigned to the desired pages and appear in the correct order from left to right. Sometimes the tabs have the titles of the desired pages and their favicons despite being like new tabs in other respects, but more often they just appear as normal new tabs.

Further details part 2: from my fiddling around trying to find a fix, the problems worsen sometimes, but othertimes improve. I have yet to figure out a pattern with this or clues for how to move forward.

Further details part 3: results obtained from Firefox History Scrounger at https://www.jeffersonscher.com/ffu/scrounger.html somewhat map to the behaviours described above, but unsure what to do with this behaviour. Some tabs show up here as much older than those displayed at the time even though the time stamps on the files in the folder all seem correct. The back/forward history view suggests related sessionstore glitches.

Thoughts on possible cause: - corrupted sessionstorebackups-backups and/or xulstore.json, but unsure how to remedy these since suggestions did not work. - some kind of timestamp issue creating some fallback weirdness (unsure if this is possible) - being too addled to notice some obvious settings conflict

On the plus side, I don't tend to have more than 8 tabs open at a time with some constants, very rarely more than one window and never more than two windows, so restoring stuff manually isn't as much of a headache for me as it might be for most users.

Would really love some help with this as really lost and confused at this point. My apologies for the garbled account.

I need to create a new profile because I am having problems, the old one appears to be corrupt. I need to keep all my extensions, settings, history, tabs, bookmarks, etc.

So from the profile that has all the settings, I tell Firefox Sync to sync. It says it's syncing.

Then I quit Firefox, open with the profile manager, create a new blank profile, and sign into Firefox Sync using the same Firefox Account.

Within a few minutes, sync completes, and my new browser profile is exactly like an old copy of firefox that I deleted maybe 5 years ago. All my old extensions, tabs, everything.

I need to sync my CURRENT Firefox so I can restore a clean profile to it. Not restore a setup from a copy I deleted years ago.

I've tried this process about 4 times now and the result is always the same. Firefox sync does NOT see my current tabs, extensions, bookmarks, settings, anything. It keeps the ones from years ago no matter what.

I don't want to delete my firefox account and start a new one because it will cause me to lose access to all my forum comments.

youtube hasnt worked in my firefox browser on my mac for well over a year. if I go to the youtube page in firefox it will maybe load the first 1 second of a video and then pause. if i click play it will advance one frame and keep going ahead one frame at a time every time i click play. oddly for that one frame it plays i will hear a split second of audio that goes with it. but the video will not just play.

i have the most updated firefox 106.0.4 I have tried clearing my cookies and cache. i have tried turning off hardware acceleration. I have tried disabling ad blocker for youtube's site. Youtube works in other browsers like chrome and safari.

any thoughts?

I want to know what caused the Firefox icon to disappear from my dock and be replaced by the generic icon. Firefox seems to continue to work well. I don't want to re-install it when it seems to work. However, I want to know what caused this to happen and if there is an easy way to restore it to the unique icon. I've read about the various remedies but don't want to take the time for a re-install when everything seems to be working.

Please just tell me the cause and if there is an easy solution.

I really like the new Firefox View, but I'd love to be able to get to the view with a keyboard command. I tried treating like the first tab (Cmd+1), but that doesn't work, nor does Cmd+0. Hovering over it doesn't reveal a keyboard shortcut. It doesn't appear on any of the menus, so I'm at a loss as to how to assign a custom control.

Thanks so much!

I think Firefox just updated to 106.0.1 (64-bit). Since then I am not able to play videos on certain sites that I need to for work. I get a message "This video cannot be played (error code 224003)" This happened last year and I can't figure out how I fixed it other than it is definitely Firefox.

The website that breaks is: https://travelfilmarchive.com/home.php

Since update 106, there is a new dock icon for Firefox on MacOS tailored for Big Sur an above. I'm still using Mojave for 32bit apps, and it doesn't look as good. Can we have an option to revert back to the old dock icon?

I'd appreciate easy to follow steps (for the last version of Firefox for a Mac using Mojave) to locate cookies for only ONE SPECIFIC website and delete them.

Thanks.

A few weeks ago, every time I downloaded an attachment from Gmail, I would tell Firefox where to put the file, but I would always get an extra copy in my Downloads folder that I would have to delete.

About 4 weeks after that (after a Firefox update, I think), Firefox stopped doing this unwanted behavior.

Now (after a recent update, I think), it started doing it again.

Why is it doing this? How do I get it to stop this unwanted behavior?

I use Mac with different tabs placed in different Desktops. Example: FF Tab1 on Desktop1 FF Tab2 and FF Tab3 on Desktop3

When for any reason (mac crash and or Restart of Maxc) When I restart FF and reopen previously closed FF Tabs --> ALL FF Tabs are packed in Desktop1. All other Desktops have no more my previously Tabs I had to (FF Tab2 and Tab3 in previous example are now in Desktop1 instead of being in Desktop3).

Any solution to fix this? Thank you
