Firefox Community Forum

Why don't I see the review checker on Amazon anymore, I liked it but it seems to be missing. I tried following the instructions but I don't see the mentioned icon that I am suppose to click on

I am reaching out to seek assistance with a recurring issue we are experiencing in the Mozilla Firefox browser.

Issue Description: On the user's first visit to the page, the thumbnail fails to load and displays a black screen instead of the intended image. This issue is observed specifically in Firefox, while the same functionality works seamlessly across other browsers.

Steps to Reproduce: Open our webpage in Mozilla Firefox. Ensure it is the first visit (clear cache if necessary). Observe the thumbnail image section.

Expected Behavior: The thumbnail should load and display the intended image correctly.

Actual Behavior: The thumbnail displays a black screen instead.

Troubleshooting Steps Taken: Verified server response and headers; no anomalies found. Checked CORS policies and ensured they are configured correctly. Tested in other browsers (Chrome, Edge, etc.), where the issue does not occur.

Request for Assistance: Could you please help us identify if this issue is related to:

Any specific Firefox rendering engine behavior? Known bugs or limitations in handling thumbnails or images on the first load? Additional configurations we might need to implement for Firefox compatibility?

I just set up a server with linux Ubuntu 24.04 Desktop, with Firefox 129.0.2 included to do some dev and testing work.

Problem: Firefox seems unable to see or open files that are above or outside the user's home dir tree.

The only extra packages installed are the LAMP stack and Google Chrome, which has no problem. (had to have something for A/B testing.)

I've tried entering the url of file:///var/www/index.html, I've tried selecting 'open with...' from the files app, etc. Nothing works.

I can get to the file through http://localserver/index.html with no issues. I've verified permissions on the entire directory tree to the file. Everything from end to end has read permissions for all, 755.

I've checked the following advanced settings: security.sandbox.content.level..............................0 (started at 4, now at 0, no effect or change.) security.fileuri.strict_origin_policy.........................false (default setting as installed.)

I am able to open file:/// and get a dir listing. BUT, if I click on var, it gives "Access to the file was denied." I even tried changing the permissions on /var to 777, but no change.

This seems to be a Firefox only problem, since Google Chrome works where firefox doesn't.

I've spent several hours searching for ways to fix this, all with no success. Does anyone have any idea how to fix this, or even what to look at???

The list of previously visited sites in firefox windows seems to have shrunk in some recent update of firefox. Now, when I click the address bar I only get 5 options, the first being search with google and the remaining 4 being previously visited sites. Used to be that list was much longer. Is there a way to customize this, or revert it back to where it contains 10+ items?

I have had a series fo problems over the last 2 months. All different, but on closer inspection, all connected to recaptcha and login security.

I have not been able to log into my wordpress admin website for 2 months. It just hangs with"Verifying you are not a robot". I can login using Chrome.

Now I have just taken out insurance for my car and have set up a login for my insurance portal - and can't login because "Recaptcha cannot determine that you are a human".

I have searched and found that there was a bug with recaptcha and firefox, but that this was fixed. In any case, this fix did not work for me.

Can anyone please tell me what I should do so that I can login to recaptcha sites?

Linux Mint (up to date) Firefox 130.0

From jscher2000 - Support Volunteer answering my previous question: His response to me: Hi, do you mean the sidebar that you can optionally open on the left side (Ctrl+B) or the Toolbar you can optionally open below the address bar (Ctrl+Shift+B)? In another thread, someone mentioned there is a new option for the sidebar to "collapse" which I guess means to close itself, but that isn't happening on mine yet. Perhaps it is an experimental option that is currently in testing. To roll back your sidebar to the classic behavior, you could try the following: (1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk. More info on about:config: Configuration Editor for Firefox. The moderators would like us to remind you that changes made through this back door aren't fully supported and aren't guaranteed to continue working in the future. (2) In the search box in the page, type or paste sidebar.revamp and pause while the list is filtered (3) If the preference is set to true, double-click it (or click the Toggle button at the right end of the row) to switch the value from true to false Any difference?

CLARIFICATION OF MY QUESTION: I checked the way you said and the sidebar.revamp already says false. What I am talking about is as follows: In the windows 10 we had, and using Firefox, there was the complete My Bookmaks list on the left side, from top to bottom. Those not showing I could scroll down through them. It also had a search bar where I could search for a sepcific bookmark. (I have had 2 strokes and I cannot remember things if I can't see it as I do it.) NOW, however, with Windows 11, there is a "tab" I guess you call it on the left end of the ribbon. If I click on that, the My Bookmarks expands down (like it did look before) and I can scroll down if the one I am looking for is below the shown part of the list. HOWever, if I go to type anything outside of that list, it collapses back to the tab. It also does NOT have the search bar for the bookmarks at all. So if I cannot remember where the bookmark is located (I have 95 bookmarks) I have to scroll down through most of them to find it. What I want is for the entire bookmark list to REMAIN visible or on top when I am doing other things. Ialso would like to be able to search for a specific bookmark which would bring it right up.

I HAVE USED THE YOUCARE SEARCH ENGINE FOR OVER A YEAR AND FOUND IT EXCELLENT, I'VE PROVIDED OVER 85 MEALS FOR ANIMALS IN SHELTERS, BUT YESTERDAY WHEN I WANTED TO DO A SEARCH, NOTHING CAME UP, IT JUST SAID 'NO RESULTS FOUND' I TRIED SOME COMMON SITES, NEXT, ARGOS, ALDI, AND IT JUST SAID THE SAME THING.

                                                                                              COULD YOU PLEASE HELP PUT THIS RIGHT,
                                                                                                                                                                    MANY THANKS, JANET.

And once again Mozilla managed to break with Firefox CSS scripts! (V131.x) The one thing that guaranteed always works with every update is that something doesn't work! The constant updates and the resulting "verschlimmbessern" until nothing works in a more. With every update there is another plug-in that doesn't work or has not been updated anymore as well.

V 130.x Outkick.com page does not load only a little bit of unformatted text. Foxweather.com images are huge page doesn't load completely. PG&E.com does not load billing information, blank page. Just to mention a few...

I have stopped recommending my clients Firefox I will no longer install it.

Dzień dobry,

Piszę z sugestią, aby przy następnych aktualizacjach wprowadzili Państwo możliwość blokowania fraz w wyszukiwarkach, zwłaszcza tych kierujących do stron dla dorosłych. Chodzi mi o to, aby wpisując słowo np. "sex" w Google, czy na innych portalach z wyszukiwarką, takich jak YouTube, Facebook itp., Firefox od razu blokował stronę, wykrywając słowo wpisane na listę do natychmiastowego blokowania. Kontrole rodzicielskie i dodatki skupiają się głównie na blokowaniu całych stron www, co sprawia, że niektóre strony obchodzą te blokady, tworząc różne wersje nazewnictwa (co sprawie, że programy są skuteczne w max. 80%). Na przykład, strona xxx może mieć kilka wersji nazwy, jak xhamster. W efekcie programy lub dodatki blokują główną stronę, ale wersje z alternatywnymi nazwami już nie.

Stąd moja propozycja, aby była możliwość wpisania listy blokowanych fraz. Gdy dana osoba wpisze zablokowane słowo np. wspomnianą frazę "sex" w wyszukiwarce, przeglądarka powinna odmówić jakiejkolwiek operacji. Proszę o rozważenie tej ważnej z punktu widzenia bezpieczeństwa propozycji. Jeśli mają Państwo możliwość zaproponowania blokowania fraz już teraz, proszę o instrukcje. Będę wdzięczny za pomoc. Z poważaniem, Krzysztof

Firefox flashes a white screen when loading a new page. This is a known issue. Is there a way to make it stop?

I see numerous people looking for answers (on mozilla, on stackoverflow, on superuser, on reddit, and on mozillazine), and I see no answers that work.

Is there a solution that works?

Does anyone know why Mozilla programs this in? (Is there a way to ask Mozilla directly?)

Firefox has been the only browser for me over the years, allowing customizations that free me from the frustrations of Chrome, Safari, et al. But why this flashbang, as kartana put it on reddit?

I've just updated from Firefox 101.0.1 to Firefox ESR 115.18.0 (I'm still using Windows 7, so can't get a more recent release). I have a program which reads a cURL command from the clipboard then runs cURL repeatedly with slightly modified versions of the command. The command is read from the clipboard rather than pasted into the command prompt window because it may be more than 4096 characters. This no longer works with the updated version of Firefox. Comparing the cURL commands from the two versions of Firefox showed lots of "^" characters had been added. For example "120Months|Yield|RiskScore" had become "120Months^|Yield^|RiskScore". When I edited the cURL command to remove the "^" characters, everything worked like it had before the Firefox update. I suspect this is related to the changes introduced by Bug 1777800. I would like to know whether the problem can be reproduced using up-to-date versions of Firefox and Windows. Starting with web page https://www.trustnet.com/fund/price-performance/t/investment-trusts?norisk=true&PageSize=25 use the network monitor to capture the result of moving to the next page of data, Copy as cURL (Windows) and use the result. Do you get a response containing the data for the next 25 funds or a very small file containing an error message?

'Another' Issue With Firefox:

On my desktop, I view Facebook via the Firefox browser. When viewing posts from other people, the date/time stamp is no longer visible.

Instead, it shows a random series of numbers and digits. However, 'hovering' over it displays the date and time.

Refreshing the page does not work. The issue also occurs on Opera.

'Again,' am I missing an 'obvious' detail here?

Is there a way of changing/removing the independence of browser windows?

Whenever I have multiple windows and close one them I cannot retrieve them, re-opening closed tabs doesn't work, since it only works on their own window.

Is there a way to change this behaviour?

I hope I have explained myself, thanks.

Hello

One morning about a week ago I woke up and opened my computer. Some update has probably been installed, and all the tab groups that I have diligently organized and saved - disappeared!

The tabs disappeared and all the sites saved within them disappeared also.

Please your help

Machine: Dell Inspiron 15 5567

CPU: Intel i5-7200U

Op Sys: Ubuntu 24.04.1 LTS

RAM: 16GB

GPUs:

(1) Integrated Intel(R) HD Graphics 620 (KBL GT2)

(2) AMD Radeon R7 M445

Soon after installing Ubuntu 24.04 LTS freshly into my laptop I followed standard configurations to set my graphics card as the primary display renderer for my machine.

This is done by setting the environment variable DRI_PRIME=1 in my .profile file and rebooting.

I also made the following settings to Firefox's about:config

         layers.acceleration.force-enabled               true

        gfx.webrender.all                                           true

After reboot I get a lot of flicker on Firefox and a lesser amount on Thunderbird. The image below flickers on and off the screen for 1-4 seconds.

No such flickering occurs on Chrome browser.

Is there any way to fix this flickering ?
