Diễn đàn hỗ trợ Firefox

All of a sudden I could not access our local electronic paper with FireFox. As it turn out the problem was caused by my virus protection software had the "Ad Blocker" turned on. When I turned the option off then I could access the paper. I called customer service and they evidently had done something with ads, but the person I was talking with could not tell me what it was. There suggestion was to use a browser that did not block ads regardless of the setting of my virus protection software. I do not understand how a browser can override the setting in my virus protection software.

My question is does FireFox have an option to turn off an ad blocker for a given URL?

In February this year I started having an issue with reading pdf formatted statements from my bank' (bank and personal information removed). Initially I thought it was some change at the bank so I sent the letter below to my bank.

Further experimenting with Microsoft Edge and Firefox leads me to believe the issue may be with recent changes to firefox. The attached jpg file shows the problem, though not a solution.

I would be curious to know if there is some (new) setting in Firefox to correct the problem.

re: document access on site

You have evidently made some changes in your account display and I have to tell you there are issues with it.

Previously the account document came up as PDF. Today I accessed the current statement and immediately noticed the change in display format.

I usually do two things here. First I print the document. The print button worked as expected. Next I SAVE a copy for future reference. The download button DID NOT WORK.

I had to use the print save to file function. This is where I found the problem. I saw this when I checked my print queue as well. Instead of PDF the document is now PDF.js viewer.

I have to ask why you went to java script when the original PDF format worked properly every time?

On the plus side, my pdf viewer still reads the saved file. It is the unnecessary print to file step to which I object.

I am not at all happy with this change and would encourage you to return to the previous process. Since it was NOT BROKE I am at a lost to understand WHY YOU FIXED IT.

The same thing happens on my two Dell laptops (Inspiron and Latitude), and a Hyper-V VM (on my desktop PC). They all run Bazzite Linux 6.17.7-ba25.fc43.x86_64.

A video may play for a second or two, and then it's either a black screen, or an error message of "The content doesn't seem to be working."

On the same two laptops and VM, the Chromium Browser, and LibreWolf (a fork of Firefox?), have no issues playing the same videos.

Firefox version on all three systems is 147.0.3.

Any help/guidance welcome with thanks.

I am running Firefox 149.0 (64-bit) on Windows 10. FF tells me that there is an update. I downloaded the update, and when I restart FF, it does not update. Version 149.0 is re-started, and Help --> About Firefox again tells me to restart to upgrade. I have tried the upgrade at least three times.

When opening the "Show all history" window (command Y) the text is garbled. I have checked the font book and there are no duplicated and I have validated all fonts. I have tried using the troubleshoot mode and occasionally the text is rendered correctly but mostly it has no effect. There is no other location in the browser where the text is garbled. I have tried changing the text in the advanced settings and both performance settings are disabled.

I am running Firefox on Kubuntu, which means it comes pre-installed as a Flatpak.

I was having problems with various web sites so I decided to try using the version of Firefox installed with the file found here - https://www.firefox.com/en-US/thanks/

There were no problems with the install. This version of Firefox showed the same issues as the Flatpak version, so I blame the web sites.

Now I have two versions of Firefox. I would like to remove this second version but all the methods I've found do not remove it. I can certainly disable it by renaming the directory created in my user directory /Firefox. Trouble is, shortcuts I created to web sites always launch this version rather than the Flatpak version and I can't find a way to get the shortcuts to use the Flatpak version.

When using the built-in Firefox AI sidebar and clicking the "Summarize page" button, I consistently get the error: "431 Request Header Fields Too Large" from chatgpt.com.

Cookies were cleared multiple times Extensions (including AdGuard) were disabled The issue persists

Previously, changing a privacy setting temporarily helped: switching from "block all cross-site cookies" to "block cross-site tracking cookies and isolate other cross-site cookies". After that, the feature started working.

However, after restarting the browser today, the issue returned, and changing this setting no longer helps.

I would also like to note that currently there is no way to disable or hide the "Summarize page" button, even though I did not need it initially. I tried to configure things so it would work properly, but was unable to do so.

Steps to reproduce:

Open any webpage Open the Firefox AI sidebar Click "Summarize page" Observe error 431

Expected behavior: Page summary should be generated successfully.

Actual behavior: The request fails with HTTP 431 error.

AV1 Hardware Acceleration stopped working. In about:support->Media->Codec Support Information Firefox states that Harware Decode AV1 is supported but it uses only Software Decoding. AV1 worked perfeclty before in Firefox, is still working in other browsers and apps in my system.

Hey there Mozilla team, Love the new free built-in VPN for the browser and Kit. :D But I have problems with enabling the VPN. I am on Linux Kubuntu and the VPN cannot start. Funnily enough when i turn on Mozilla VPN on device level the Browser VPN does manage the enable itself.

Also I have a question about the Mozilla VPN browser extension. Is support for Linux still being worked on? And could we see the support being implemented soon?

Have a wonderful Day

Hi, the home page shortcuts used to be bookmarked sites I selected, and they stayed in one place. After a recent update Firefox litters the page with recent searches, displacing the ones I saved. I can't see a setting to select recent search shortcuts ON/OFF, how to restore the old (and very useful) shortcuts?
