Webpages saved as PDFs using FF are very large files compared to the same webpage saved as a PDF using Safari. FF will create a 2-3 page pdf that is over 3 MB of data, while Safari saves the same pdf as 325KB. I never noticed this to be the case in the distant past but as my available storage space started shrinking rapidly on my MacBook I realized this might be the culprit.

I don't know when these large pdfs files started with FF but as I reviewed some similar files from several years ago, the same type of 2-3 page pdf in FF was in the KB, not MB of data. Can anyone help me understand why this is happening? Is there a setting that should be changed so these pdfs are not so bloated in size?

I am still using FF 88.0.1 having not made the leap to the newer versions of FF because of all the bad reviews. That said, I have not seen any info which indicates that FF scaled down pdf file sizes in the newer versions of FF.

In FF's Preferences pane PDFs are set to open in FF. Would it help reduce the file sizes if I changed that so they open in Mac's default application which I assume is Preview? I don't know if that's what the default preference was years ago when FF pdfs were much smaller files, or if changing that would make no difference at all.

Also, for what it's worth, I previously disabled FF's new-ish Print Preview Interface in about:config because it was consistently overriding the preset positions I set for my headers and footers, resulting in them being cut off the printed pages, however, the bloated pdfs were a problem long before FF introduced the Print Preview Interface feature.

Any suggestions on how to reduce the size of pdfs that FF is creating? I don't have and don't want to get a 3rd party application like Adobe Acrobat to deal with this, when I can simply use Safari as my browser. Thank you.

I have made Firefox my default browser on my laptop. When reviewing my account I noticed that the original username (e-mail address) I created the account with no longer exists. Is it possible to replace my new e-mail address for the old one, and use it as the new User Name?

  Thanks in advance for your help.

even when disabled my background colour keeps reverting to black in firefox I have disbled dark option in themes but it still reverts. I have set text to black and background to white.

PLEASE think of the end-user for ONCE in your developer's life and STOP moving around the option to take screenshots please!!! First it was in the right-click menu (best option, I still try to find it there every single time just like the Copy and Paste options) then you moved it to the "..." address bar menu, and now it was removed once again and the user must customize the toolbar to add the button?? Seriously? Who thought this would be more user friendly? Please provide a single reason to justify this Microsoft-ish behaviour.

Surely the option will be completely removed in next version, to force users to return to a previous version.

PS. did Yahoo already acquire Mozilla? That would explain a lot.

Proton is crap. Low contrast high space and infuriatingly enlarged vs the old standard. Screens are getting larger but that means users are expecting more information on them not less. I actually reverted to either v88 over proton. Is the option to turn it off back yet or is still use custom css and hope they don't break that every update?

I cannot access access Ancestry.ca due to a Firefox Browser Validation Error 54. Ancestry says this is a client side problem, it is not on their side. Sometimes I can access and sign in the website with no problems, then when I sign out, I cannot sign in due to a Firefox Browser Validation Error 54 again. This has been ongoing for about four months. How can I fix this Browser Validation Error 54 so I can access Ancestry.ca.

Last time I updated Firefox all menus and settings were lost. How can I avoid that? Yes, I know the answer is "that shouldn't happen" but it did and took my software engineer husband an hour to figure out how to get them back. Would like to skip that step. It's been more than a year since I updated but I'm now getting error messages saying my browser is out of date and website cannot be used without an update. Help!

The search engines I've added do not appear in the list after clicking the green + sign in the search box and they do not appear in the list in the options either. I used the "add more search engines" found in the bottom of the search engines list to find the missing engines and add them again, but when I find the engine I want to add there is only the "remove" button. So this tells me the missing engines in the list are still there but not accessible. I tried removing the added search engine and then adding it again but this did not make them appear in the search engine list. Everything was working fine until getting the last update before Firefox 89. Is there a way to fix this???

Preview is opened as default when printing. I prefer to use the system printing. How can I discard Preview? The printing task now takes more than a minute to access the printer. It all started since Preview was introduced as default! Meanwhile Firefox i locked and I can't do anything in Firefox.

I still have v88 of Firefox. I was automatically upgraded a few months back to v90 I think and there was no "file edit view history bookmarks tools and help" at the TOP of my screen like it has been forever! I use my bookmarks from the top of my screen all the time, that's how i get to all my websites. I found it in the side bar (right hand side I think, which is a horrible place for that)

Before I decide to upgrade to v94 (which says is the newest version) is there a way to put the "file edit view history bookmarks tools and help" buttons back at the TOP of the page and not in the stupid hamburger menu thing.

If memory serves me correctly the startup page also didnt have the "most viewed" sites or only have 5/6 and no ability to have 16 options, is that a thing still?

I'm a basic user who hates change when nothing was wrong with how it was before for the past 20 years lol

Thanks for any assistance!

I downloaded the new version, 89.0.2, not realizing how really horrible it is. Since, trying to return to the old version (88.0.1), I've managed to delete my entire firefox directory, and have to reinstall FF from scratch. I've lost all history and bookmarks for the past 10 years. I can get by that. But, how do I set a photo from my pictures library to my FF homepage? Thanks for any relevant responses.

hi. i was debugging my Django_React project in inspect element mode of firefox and that was my first time doing that so i was confused and clicking on some buttons to get to know what to do and outta no where that page crashed. i did rerun my whole project and tried again to connect to it but doesnt work. i checked, the firefox is up to date. i ran firefox in troubleshoot mode and reran the project but still doesnt work and crashes. i think it is not about my hardware or firewall options.

the FIRST REPORT ID that i got is: "bp-cd41341c-37e7-4c5d-9494-f85340211026"

the LAST REPORT ID that i got after the whole project rerun and in troubleshoot mode is: "bp-228837ce-f0d5-4767-981c-46f240211026"

I have hit what appears to be a "YouTube TV" (vs YouTube) buffering problem. It happens only with Firefox on my PCs. After a few seconds to a minute of playing a TV program or movie, the video/audio stops with a spinning arrow. If I previously had turned on "stats for nerds" to monitor this, I can see when network activity stops and the buffer then eventually gets exhausted.

This does NOT happen when running YouTube TV on my TVs or on my iPhone. Probably more significant, it does NOT happen with YouTube TV under either Microsoft Edge or Google Chrome on these PCs. If I run Firefox in Troubleshoot Mode, i.e., no add-ons, extensions, etc., the problem still exists, so it is not just some rogue add-on, but is related to Firefox itself. The problem appears to be only for "YouTube TV" on Firefox since, for example, videos played from YouTube (vs "YouTube TV") do not have the problem under Firefox.

I tried rebooting my router as well as the PCs. The problem still existed. The PCs are high speed and the internet connection is fiber optic. One of the PCs is connected by Ethernet; the other is wireless. Download/upload speeds are over 900 Mbps on the Ethernet PC. I have not seen slow network indications on anything except this "YouTube TV" with Firefox mixture. Hardware does not seem to be the issue.

Apparently the problem is software. I also tried temporarily disabling my antivirus/firewall software. No change. I'm running Windows 10 version 21H1 and Firefox 88.0.1. I'm new to YouTube TV; although most of my viewing with it has been done on TVs, I don't recall seeing this problem in my PC tests a month or so ago.

Hi,

I'd like to use keyboard media keys (play/pause, prev, next) to control Spotify web player and Youtube but they don't work. The option is enabled. I'm using Firefox 88.0 on Windows 8.1, so according to this article it should be supported. The keys work on other apps. I've tried in troubleshooting mode as well, no luck. Any ideas?

When I try to print from Firefox 88 on my Mac Laptop running OSX 10.12.6 the new print preview window takes a very long time to load the preview before I can print. I could not find a work around.

I tried switching to the Classic print system via (print.tab_modal.enabled - False) Now I don't have the preview to deal with so I can print immediately like I used to. However, if I try to open a PDF in Preview from the Print Dialog window, it takes a very long time to load the preview which it did not do in earlier versions of Firefox.

I am surmising that one of the Firefox updates added the print preview function which doesn't work quite right on my Mac.

Any ideas would be appreciated. Andy

So after 13 years, Mozilla has changed the shortcut for "Copy link" from A to L.

This is an INSANE move! Copying links isn't some obscure power command, it's a basic, everyday function that everyone needs to use. Who doesn't have to copy URL links from time to time?

Moving the key to L makes the shortcut so much more difficult to use now. You're required to move your left hand a long way, and look down at the keys. It takes forever and interrupts the flow of browsing the web. It's stupid. Why not change the key to C? Isn't that logical?

I wish I could give Mozilla feedback about this, but sadly I can't.

Can someone please tell me how to change this back WITHOUT installing an extension. If Mozilla have just suddenly changed this key without even giving users an option to change it back, that is terrible.

On some websites (e.g. the Guardian newspaper) Firefox displays graphics overlaying the text, making the page unreadable. Same page works fine in Chrome. Thoughts?

Hi, none of the videos appear/play on this CNN site that is all about videos. Only still shots appear. The videos play in Chrome. Here is the site: https://www.cnn.com/2021/04/23/world/videos-of-the-week-mobile-april-23/index.html

I've already tried toggling the "Enhanced Protection" switch off and on to no effect. I don't see any option for enabling/disabling permissions for audio/video in the address bar as appear on other sites offering video or audio. Thanks for any remedies.

Hey there,

for a while now we have problems loading our page https://risofort.press/ in firefox: the header will always load, the body of the main page and sub pages will infrequently load, and after having loaded once it will not reload for a long time (like, weeks). all of this works in other browsers. After contacting our host and trying some stuff like deactivating plugins to see if one them is causing it, I am realizing that perhaps it is the way our theme is loaded by firefox - a similiar issue was resolved here: https://support.mozilla.org/de/questions/1320526#answer-1381654

However I can't figure out what part of our website is the one that is keeping the main area to be loaded, or become visible, rather.

Any thoughts on this very welcome, thank you! Will also pass this question on to the theme authors.

Thanks in advance, L.
