Diễn đàn hỗ trợ Firefox

I've been using my banking site for many years on my desktop computer. Today the site comes up but when I try to log in I get a "404" error message. I tried logging in with Edge and there was no problem. I have deleted all my banking cookies on Mozilla and the result is the same. This is a major problem and I would appreciate any suggestions.

Hi, lately I have been trying to tackle my secondary HDD being spun up for no reason in the background and one thing that keeps popping up is Firefox.exe accessing a bunch of fonts contained in the Solidworks installation on the HDD (which is a secondary drive, while Firefox is installed on the primary SSD).

I really cannot understand why it happens, since I think nobody is supposed to install Solidworks along with Firefox. Of course I don't want this activity to wake up my drive, but also, is it normal? I have to admit I'm kinda worried.

I'll attach screenshots from Sysinternals Process Monitor

Thanks in advance to anyone that will help :)

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.

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!

Tried to use doxy for a video call. Said I needed to refresh to load most updated browser. Once I did that, it says doxy has no access to webcam. I cannot figure out how to change that.

Thanks

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.

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???

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!

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.

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?

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.

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.

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.

My primary machine has (FF 88.0.1 64-bit) has all the FF tweaks for privacy and annoyances I care to have. Last outstanding issue is floating videos -- but that's posted as another topic by me. Big questions:

1. Can I bring FF on the three other laptops and server to the same FF revision level at this machine and copy across all files that would capture settings this machine's settings/changes in Config and Policies ?

I currently make quick work of syncing UBlock and AdBlocker on all machines by simple export/imports of text files. Everything tweaked exactly the same on every machine with respect to FF is what I am after...

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.

Greetings. How do I set a photo from my pictures library to my FF homepage? I asked this several months ago, figured it out, then lost it again, and can't regain. I'm using v88.0.1, because the update to 90 doesn't work for me, so I assume anything later won't either, if it's built on top of it. Thanks for any relevant responses or suggestions.

I just installed Firefox to my laptop and noticed that Japanese characters are not working. I tried to change the language from english to japanese because I thought it would install the characters but didn't work and rolled back to english. I need to read japanese texts in webpages.... I also checked text decoding from settings > more > text decoding. Unicode is selected and I cannot change to anything else, it is unselectible. What should I do to be able to use the browser properly?

I am frequently having problems trying to log in to online bank Simplii Financial. My internet connection is good, FF (88.0) is able to connect to other sites. Other browsers (Opera, Chrome etc ) could all connect and allow my login. With FF it simply continues loading with no result. i have asked the bank to check their FF certificates? and they say there is no problem - just use another browser! Firefox is my main browser, the only one that can save my login details. This problem is sporadic but has been going on for several months. It may be connected with FF updates but I am om the latest version for my Linux distribution I believe.

 At one time FF would never connect to PC Optimum whereas other browsers did, that problem was somehow solved.
