Diễn đàn hỗ trợ Firefox

I've been using Firefox browser for Facebook and other online purposes for several years. Over much of that time I periodically (several times per week, minimum) get a small pop-up box, usually while I'm on Facebook, which is headed "Apple wants to make changes. Enter your password" The "USERNAME" box shows only my first name, John, (which is my admin password for the laptop) and the "PASSWORD" box is empty. No indication of what changes Apple wants to make, so I've never put my password in, and when I hit "cancel" I have to cancel three times before it goes away, only to show up sometimes within minutes, or sometimes days. Until today I'd not been able to get a diagnosis from Apple, but their help person, after a screen-sharing session today said it doesn't come from Apple and she suggested I contact Firefox Support and ask about it. So I'm asking. The screen shot below shows what it looks like, although I closed Firefox before i took this screen shot, just to see if the box would remain, and obviously, it did. Any thoughts as to whether this is somehow coming from Firefox? Thanks, John Jessup

From my adobe account, I try to launch my web based apps so I can use the web based adobe acrobat, and the browser page opens as a blank screen only. I am on an older mac book w/ Yosemite 10.10.5 and Firefox is up to date wiht 78.15.0esr (64-bit). Please help! I need to be able to manipulate pdfs. Thank you

I get this error message and then it shuts down if I don't stop it by deleting it....

“Error while installing” :Expecting value: line 1 column 1 (char 0) Fire Fox then shuts down if I don’t delete it.

Hi there, Please see attached image of screenshots of searches on Firefox and Chrome. The Firefox search images are incomplete whereas the Chrome images are complete. This has only started happening on Firefox recently. Can you please help me resolve this issue. I have cleared the cache & cookies, restarted my macbook etc but nothing has worked. Thanks in advance, Paul

Hello,

I know this question is probably somewhere here but I can't find the answer (what I tried below).

So, I have a Debian 10 computer, with Firefox 78.15.0esr. I'm using the Adwaita (dark version) theme on my OS.

The problem is that Firefox uses the dark theme in Its menus (I don't mind) but It transmits to websites this setting and thus, websites supporting dark mode use it (Google, DuckDuckGo for example). I don't like that. I want them to use the light mode but keeping my theme on my OS.

So, I tried to change the value to 0, 1, 2, 3 (I tried each for them) for the setting layout.css.prefers-color-scheme.content-override and put "Adwaita:light" in the widget.content.gtk-theme-override field in about:config. Each time I restarted Firefox. It never works, websites still continue to use the dark theme...

Thanks in advance

I am no longer able to log in to eBay using Firefox. I am using Firefox 78.15esu bc I have an older Mac that will only support up to Mac OSX 10.11. I was able to use eBay up until this morning when the site asked me to log in again... and verify that I am indeed a human through the hCaptcha checker. The checker cycles between identifying horses and lions... and every time, I seem to pass but then comes the message "Failed to pass Captcha, Please try again." I can access eBay using Safari and Chrome. Right before the failure today, the rendering of the eBay pages was odd... needed 3x the screen width to see the whole page. eBay says that the problem is on the Mozilla side of this issue... mostly because I can use a different browser without problem. I think I am in agreement with them. I don't really want to use a different browser but I will bc I like eBay, too. Please advise.

Hi All,

I'm using an iMac with OS X El Capitan 10.11.6. I am using Firefox 78.15. When I click on links, nothing happens. I have to right click and select "open link in new tab." I suspected it might be an out-of-date Add-On. So, I disabled all add-ons and restarted Firefox. It had no effect.

This problem is getting annoying Any assistance is greatly appreciated.

I accidentally deleted the blue star on one of my book-marked items and am struggling to get it back. Its very useful so i can see immediately if somethings already been bookmarked. Plus I could remove easily and/or put into other folders. All solutions appear to be to go to customize firefox and to drag and drop in some bar at the top of the page BUT when i do this it STILL doesn't come back. HELP!!! (Please explain in total laymens terms and don't nauseate me with technolingo.)

There are 2 processes involved in Firefox Sync, and 0 differentiation between them in the language used to describe what Firefox Sync does in any of the documentation, this makes nearly every discussion on the topic highly confusing to borderline misleading.

When you press Sync, you are pushing settings to Firefox servers. When you sign in to Sync, you are pulling settings from Firefox servers.

Both of these steps are referred to interchangeably as "syncing" and there is next to no documentation of what causes each to occur nor what they actually do.

Why is this dangerous you might ask? Well, let's say I buy a new computer, I want to set it up the same way I use all my devices, so I sign in to sync to synchronize my settings, makes perfect sense. Nothing tells me anything is happening when I sign in, so I click the sync button because I want to synchronize my settings with my other devices. Big mistake. I've just overwritten the server-side sync profile with a default Firefox profile. You know how you fix that? You sign in and press the sync button to overwrite the sync profile again. But you know what happens when you sign in? You become synced with the now blank sync profile and lose all the settings that you want to be pushing to the sync profile. This just happened to me. Thankfully I was only choosing to sync add-ons and options AT THE TIME and I have backups that are about 6 months old and I rarely change settings, but some things like my homepage URLs are something that I do change fairly often, and I'm sure some additional sites were whitelisted since by default I just reject all cookies. I also thankfully use policies.json to block updates so I didn't immediately get assaulted by that too.

SO! I HIGHLY suggest that when merely signing in to Sync, the default should be for syncing to be off to start off with, so that you can choose what to "sync" BEFORE it occurs. However, because of the language, the question arises, what am I choosing to sync for? Am I choosing what to PULL from servers? Or am I choosing what gets PUSHED to the servers? When syncing is turned on, does that mean I an pulling the settings that I have chosen? Or am I am pulling ALL settings while only pushing what I have chosen IF I click the Sync button? Or do I push EVERYTHING?

It's incredibly unclear how the Sync feature works and both of the "main" articles on it are completely useless for understanding it because the term "sync" is used interchangeably for pushing or pulling settings.

What are the correct steps to rectify this horrid situation? Sign-in, set-up sync, choose "Options" and "Add-Ons" again, THEN copy over the backup settings, THEN Sync them to the "cloud"? If I have 2 different devices setup with sync, and 1 chooses to sync options and the other chooses to sync bookmarks, then I click sync on BOTH devices repeatedly, what occurs?

In Amazon.co.uk, when I tried to remove items for view option, the option is not working. I tried with Safari and it works?? so is it a bug with firefox or amazon, but then again why aill it work with other browser....

When I enter the address of a website that I like the browser opens a chinese version of the same website. I try changing the address repeatedly and it always goes to the chinese website.

www.lomography.com goes to lomography.cn automatically. I can't change it.

I want to view the website in English (US).

Been trying to find my way through controls to change this but to no avail.

What do I do?

Hi, my 2008 Mac Pro uses OS X El Capitan, version 10.11.6 and I am on Firefox 78.15.0esr, I cannot install the new upgrade. Can I continue using the older version of Firefox even though the sync will not work anymore?

Two questions regarding FireFox ESR for legacy macOS:

Is there any plan to make Yelp compatible with FireFox ESR? It hasn't worked correctly for a couple of years…

With the conversion from Intel to Apple Silicone macs, any idea how much longer will FireFox ESR support the Intel platform?
