Firefox 社群討論區

I am happy that FF has added great PDF capabilities. I have a problem with signatures. When I add my signature as an image, the result is a very poor resolution / quality signature image. Adobe Reader inserts the signature as a very high resolution / quality image.

Is there any update / solution to this? FYI I am using the same signature image but FF makes it BW and poor quality while Adobe Reader maintains the color and resolution.

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.

I'm having trouble downloading product specification PDFs in Firefox from Formers Paper, a thermal rolls manufacturer. Some files open correctly, while others fail to download or display properly.

Has anyone experienced similar issues when accessing documents from a thermal rolls manufacturer website? Are there any Firefox settings or troubleshooting steps I should check for PDF downloads and file handling?

Thanks for any guidance.
