Firefox: форум сообщества

When viewing pdf files created from MS Word (.docx) documents and sent to me I see white lines across some images but not all. This happens with Firefox on Windows 11 and linux mint (various versions). It is present on the images from the file as received and after uploading to a website. The images are OK if viewed using Opera or other browsers but the same problem is present on Thunderbird. The file below has the problem on 2 images when viewed on Firefox. https://www.kass.org.uk/Documents/NewsletterFrom251114/20260304%20March%20Newsletter.pdf I have caused the writer of the article a lot of trouble because I blamed her file which seems to be OK. Can you help? Thanks Brian

Hello Mozilla Support Team,

I have been using Firefox for a long time, and recently I upgraded my Windows system. Before the upgrade, I had set Firefox to open PDFs directly in a PDF Reader other than Firefox’s built-in PDF viewer, and it worked perfectly. However, after the upgrade, Firefox now shows the "Opening when completed" message and opens PDFs slowly, instead of opening them immediately in my chosen PDF Reader.

I have checked the settings, cleared the cache, refreshed Firefox, and even tested with other software, but the issue persists. The settings for handling PDFs are still the same, but they don't seem to work as they used to.

Can you please assist me in resolving this issue? Any help would be much appreciated.

Thank you

When filling in the PDF documents, at each section/line I move too, the font reverts back to the super large size, without being prompted too. Is there a way to set the font, so it remains the same, unless prompted? When attempting to adjust the font, it goes from super large to super small, any suggestions to set the font in between these two sizes?

• • I opened up the document from my email and began working from there. Should I use a PDF program and not from the email?**

Why has Mozilla decided to COMPLETELY IGNORE security settings applied to PDF documents? I have a number of PDFs secured so as to prevent the ability to print or copy text. When opened with Firefox, all of these settings are ignored.

I'm trying to use Firefox to fill out my tax forms, but while I can save them and view them with Firefox, they're blank when I open them with Adobe or print them. This is, to say the least, NOT USEFUL. What is happening?!?? I'm using Win10 and the latest version of Firefox, and I tried it on an old Mac with the latest version of Firefox as well.

While using Dext there is a visual of the uploaded pdf file. Now there is a notice that my Firefox settings need to be changed. Dext does not have instructions for Firefox and I have not yet located the spot in settings to adapt for this. Looking for directions.

I just had a Firefox update and it stated: Edit PDFs in Firefox. How do I find this feature? I've looked in settings and all things listed from the "hamburger" menu and can't find it.

idk, what i did, but i assume it's most likely user error. but i don't even know where to go from where i'm at.

ok, i'm going to attempt to identify what is happening. [guess] .pdf website previews are messing up the font when converting the .pdf to an image asset for the website to use as a current web asset, when the .pdf is updated. (makes sense really, smart drag & drop update of a .pdf menu, has instruction to make the end users browser do the work for you. kind of a one and done webpage coding for older guys that can't type, let alone edit Html, or even use Wix. some people just don't "compute" hard R or not. lol )

i don't even know where to start. i mean Mozilla is probably referencing it's own "lib.moz" which is just probably it's own personal link to an existing Lib file so it can pull it in and do what it needs to do with it without Root etc.

that is probably working fine as it renders (opens) the .pdf fine whence it's downloaded it. so all that i've talked about might not be the problem.

there is probably some mozilla function calling that to convert the .pdf as an image web asset so that it can show a preview of the current .pdf available for download.

that converter is messing up the font recognition, and building a preview image with messed up font characters (why it looks like Wing-Dings). but i don't even know where to start, and i don't think a new install will solve this (kinda overkill, and any residual files may still remain.)

i'm adding a fastfetch

[[i somewhat found an "answer" though i'd hardly call that "solved."|https://support.mozilla.org/en-US/questions/1275786#answer-1276068]]

i still say a Lib in a repo needs updated, within, or perhaps up stream of the project to reflect "commonly used fonts" if applicable (i know that's the trick, 'is it FOSS') yet other browsers use it, though idk if they're FOSS... i'd need to know what i'm looking for to confirm that or not, and do something about that (again most likely upstream, as the PDF Viewer is probably it's own project (or even several), retooled by Mozilla for Firefox.

Hi, when I work in Xero, the pdf documents will not open. Firefox is up to date and I have wiped all cookied and history. Is there anything else I need to do please?

Thanks Amanda

I opened a new window and dragged a PDF into it. While the icons in the upper right do not include Edit, I just went to the field I needed to change (an alarm permit renewal, change of email). A box opened "somewhat" over where I clicked, and I was able to enter the new email, but I could not delete the old one. After saving and opening in Acrobat, both emails are written over each other, making both unreadable.

I cannot highlight my old email in the original form in order to select Delete. When I type my new one, a trash can appears, but that is for deleting what I just entered.

Every time I open a file that is downloaded the box showing info on the highlight tool comes up and then I have to hover over it and hit escape............I do not want it to open at all so how do I stop it..............

A msg box comes up that says go to setting to enable the ability to highligh pdf's. I went to settings and did not find. this box comes in the upper right hand corner. I am usually working in PAGES. jhelp if you can. Thank you.

Hello all,

I know this feature is brand new and awesome! I have a question about the statement below from the FAQ.

What does the statement "When editing with Firefox, your documents generally stay on your local device" mean? I am just wondering about the "generally" portion.

I sometimes have to edit sensitive documents and want to make sure that this editor is a viable option. Will there be a prompt if the file has to be uploaded to a server?

Just some security concerns.

Thanks in advance for your help.

I clicked on a PDF website while searching for articles on relations between Ukrainian settlers and First Nations people. Instead of opening so I could read it, it was automatically downloaded as a file into Firefox. Unfortunately, I noticed the title had random parentheses in AFTER I clicked on it to read it. I updated Windows defender, and ran the offline scan. I also uploaded and ran MSN.com M.S.R.T. and Malware Bytes, but they found nothing.

What happened? Did I unwittingly install Russian malware into my computer, or does Fire Fox automatically download some PDF websites as files?

Thanks,

Charlotte
