The possible causes and solutions vary depending on whether you are unable to save a few specific preferences or if no preferences are saved at all. This article may also apply if, after updating Firefox, a Firefox Updated tab opens to a page stating You’ve been updated to the latest version of Firefox every time you start Firefox.

Follow the Reinstall Firefox step in the Troubleshoot and diagnose Firefox problems article to remove the Firefox program from your computer and then reinstall a new copy of Firefox. (Reinstalling Firefox this way will not remove your user data and settings, since those are saved in a separate location from the program files.)

You can save your changes to an Adobe PDF or PDF Portfolio in the original PDF or in a copy of the PDF. You can also save individual PDFs to other file formats, including text, XML, HTML, and Microsoft Word. Saving a PDF in text format allows you to use the content with a screen reader, screen magnifier, or other assistive technology.

Word Won't Save File Permission Error

If you don’t have access to the source files that created an Adobe PDF, you can still copy images and text from the PDF to use elsewhere. You can also export the PDF to a reusable format, or export images in a PDF to another format.

Adobe Acrobat Reader users can save a copy of a PDF or PDF Portfolio if the creator of the document has enabled usage rights. If a document has additional or restricted usage rights, the document message bar under the toolbar area describes the assigned restrictions or privileges.

Usethis method to save PDFs, including PDF Portfolios,and PDFs in which you have added comments, form field entries, anddigital signatures.

Note:

Saving a digitally signed PDF invalidates the signature.

• To save changes to the current file, choose File > Save.

• To save a copy of a PDF, choose File > Save As.

• In Acrobat Reader, choose File > Save As or File > Save As Other > Text.

• Starbound add mods to server. To save a copy of a PDF Portfolio, choose File >Save As Other > PDF Portfolio.

The Autosave feature guardsagainst losing your work in case of a power failure by incrementally,and at regular intervals, saving file changes to a specified location.The original file is not modified. Instead, Acrobat createsan autosave file of changes, which includes all the changes youmade to the open file since the last automatic save. The amountof new information that the autosave file contains depends on howfrequently Acrobat saves the autosavefile. If you set the autosave interval to 15 minutes, you couldlose the last 14 minutes of your work if a problem occurs. Frequentautomatic saving prevents loss of data, and is especially usefulif you make extensive changes to a document, such as by adding comments.

You can apply autosave changes to the original files when yourestart Acrobat. When you close, savemanually, or revert to the last-saved version of a file, the autosavefile is deleted.

Note:

If you use assistive technology, such as a screen reader,you may want to disable the Autosave feature so that you don’t loseyour place when the file is reloaded.

The Autosave feature won’t work in the following cases:

• A document that has its security changed. You must save the document to re-enable automatic saving of document changes.

• A document created using the Web Capture feature or extracted from a larger PDF (Tools > Organize Pages > Extract). You must save the document to enable automatic saving of changes.

• A document displayed in a web browser or incorporated into a container document that supports Object Linking and Embedding (OLE). This document appears outside the default file system and cannot support automatic saving.

Toprevent lost changes after an unexpected interruption, enable theAutosave feature, which is the default setting.

In the Preferences dialog box underCategories, select Documents.
Select Automatically Save Document Changes To TemporaryFile Every xx Minutes (1-99), and specify the number of minutes.

Start Acrobat oropen the file you were working on last.
When prompted, click Yes to open the autosave file orfiles. If multiple files were open, Acrobat opensall of the files for you.
Save the file or files with the same names as the filesyou were originally working on.

You can sometimes reduce the file size of a PDF simply by using the File > Reduce File Size, or File > Save As Other command. Reducing the size of PDFs improves their performance—particularly when they’re being opened on the web—without altering their appearance.

The Reduce File Size command resamples and recompresses images, removes embedded Base-14 fonts, and subset-embeds fonts that were left embedded. It also compresses document structure and cleans up elements such as invalid bookmarks. If the file size is already as small as possible, this command has no effect.

Note:

Reducing the file size of a digitally signed document removes the signature.

Note:

Adobe is testing the simplified optimize PDF experience with two different names - Reduce File Size or Compress PDF. Therefore, after updating to the latest release, you see either the Compress PDF option or the Reduce File Size option. From the functionality perspective, both the options are the same.

Choose the location to save the file and click Save. Acrobat DC displays a message showing the successful reduction in PDF size.

Note:

To reduce file size of multiple files, see Reduce file size of multiple PDFs.

Open a single PDF, or select one or more PDFsin a PDF Portfolio.

If you’re certain that all your users use Acrobat or Adobe Acrobat Reader, limiting compatibility to the latest version can further reduce file size.

(Optional) To apply the same settings to multiple files, click Apply To Multiple, and add the files. Click OK, then in the Output Options dialog box, specify your folder and filename preferences.

Note:

The Apply To Multiple button is not available in PDF Portfolios.

To control changes and quality trade-offs, use PDF Optimizer in Acrobat Pro, which makes more options available.
