How to downgrade back from Zotero 7?

NGO-Guy
The hard work the zotero-team put into the new version is very much appreciated. It looks good and I am sure, it will be a great next step. But since the upgrade, mdnotes and zotfile dont work anymore and the pdf-viewer is not working very well: some files just plainly dont work and in other files, some elements only show up sometimes and disappear when zooming in.
The former (plugins) was kind of expected and though sad is tolerable. The latter is very, very bad.
So, I would prefer to go back to zotero 6. Any way to do that?

    Zotero 6 is still available from the download page, but staying on Zotero 6 isn't a good option — parts will stop working eventually and you won't receive any support here for problems. So you should provide actual examples of files that aren't working well for you in Zotero 7 so that we can investigate. Zotero 7 was in beta for over a year, and we have no reason to believe there are major problems with the PDF reader.

    To replace ZotFile you can use either ZotMoov or Attanger.

    Thanks a lot for your answers - very much appreciated. I will try the suggested plugins when I upgrade again to Zotero 7. However, Zotero 7 is basically unusable for me right now, since the PDF-viewer is disfunctional for the most part: Slow and sluggish, not rendering pages etc. No problems with PDF in any other app (Firefox, Adobe, PDF24...).

    Again, you need to actually provide examples. Other people are not reporting what you're reporting.

    I will reinstall it and even try it on different machines, when I have time to do so. Could you provide some information what you need and how?
    Documents I tried:
    - https://www.circhive.eu/resources
    - https://doi.org/10.14512/9783987263361 "Faktencheck Artenvielfalt"

    - the former documents: zooming in using ctrl and mousewheel led to pages not rendering. However, if I zoomed out again and moved to previous pages, these were rendered. When I then moved down again, the previously not rendered pages were rendered again.
    - the latter document didnt open at all - this has over 1.000 pages though...

    system: Intel I7-3770, 3.4 GHZ, just noticed however, that it is still Windows 10.

    1) Could you send the 10.14512/9783987263361 file to support@zotero.org with a link to this thread?
    2) How much memory does your system have?
    3) What is your screen resolution?
  • NGO-Guy
    1) its about 120 MB, thus I cant send it. However, the download is free: https://www.oekom.de/buch/faktencheck-artenvielfalt-9783987260957 -> on the right hand side: "erhältlich als" - check "PDF 0,00€" - then you can download the document "freier download".
    2) Memory: 16GB
    3) 3840 x 2160

    Thanks, I was able to download the file. However, I haven't been able to reproduce the issue so far. Seems like an issue when there is not enough memory for Zotero.

    1) Are you using the 64-bit version of Zotero?
    2) Is there a difference if you have only one tab open compared to having multiple tabs open?
  • NGO-Guy
    1) yes, 64 bit.
    2) I tried to open it as the only tab.
    I can open it without any problems when using Zotero 6.
  • dstillman
    Can you reproduce this with all plugins disabled?
  • NGO-Guy
    since none of my plugins were working/enabled due to not being compatible with zotero 7, I can reproduce :-)
  • martynas_b
    @NGO-Guy could you test whether the integrated PDF viewer in Firefox can properly display the PDF files?
  • NGO-Guy
    Sorry - holiday. I just checked: In Firefox, the documents (including zooming in-out) are displayed without any problems.

    @NGO-Guy

    1) Is there a difference if you reduce your screen resolution?
    2) Can you provide a Debug ID for loading these PDF files?
  • martynas_b
    I'm curious if other users on this forum can reproduce the issue on Windows when zooming in on these PDF files:
